Bentonite-supported nanoscale zero-valentiron (B-nZVI) was synthesized using liquidphase reduction. The orthogonal method was used to evaluate the factors impacting Cr(VI) removal and this showed that the initial concentration of Cr(VI), pH, temperature, and B-nZVI loading were all importance factors. Characterization with scanning electron microscopy (SEM) validated the hypothesis that the presence of bentonite led to a decrease in aggregation of iron nanoparticles and a corresponding increase in the specific surface area (SSA) of the iron particles. B-nZVI with a 50% bentonite mass fraction had a SSA of 39.94m2/g, while the SSA of nZVI and bentonite was 54.04 and 6.03 m2/g, respectively. X-ray diffraction (XRD) confirmed the existence of Fe0 before the reaction and the presence of Fe (II), Fe(III) and Cr(III) after the reaction. Batch experiments revealed that the removal of Cr (VI) using B-nZVI was consistent with pseudo first-order reaction kinetics. Finally, B-nZVI was used to remediate electroplating wastewater with removal efficiencies for Cr, Pb and Cu > 90%. Reuse of B-nZVI after washing with ethylenediaminetetraacetic acid (EDTA) solution was possible but the capacity of B-nZVI for Cr(VI) removal decreased by approximately 70%.

In this study, organobentonites were prepared by modification of bentonite with various cationic surfactants, and were used to remove As(V) and As(III) from aqueous solution. The results showed that the adsorption capacities of bentonite modified with octadecyl benzyl dimethyl ammonium (SMB3) were 0.288 mg/g for As(V) and 0.102 mg/g for As(III), which were much higher compared to 0.043 and 0.036 mg/g of un-modified bentonite (UB). The adsorption kinetics were fitted well with the pseudosecond-order model with rate constants of 46.7×10−3 g/mg h for As(V) and 3.1×10−3 g/mg h for As(III), respectively. The maximum adsorption capacity of As(V) derived from the Langmuir equation reached as high as 1.48 mg/g, while the maximum adsorption capacity of As(III) was 0.82 mg/g. The adsorption of As(V) and As(III) was strongly dependent on solution pH. Addition of anions did not impact on As(III) adsorption, while they clearly suppressed adsorption of As(V). In addition, this study also showed that desorbed rates were 74.61% for As(V) and 30.32% for As(III), respectively, after regeneration of SMB3 in 0.1M HCl solution. Furthermore, in order to interpret the proposed absorption mechanism, both SMB3 andUBwere extensively characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) analyses.

Stable complexes are required during the ion chromatographic (IC) separation of Fe-polycarboxylic acid complexes. Electrospray ionization mass spectrometry (ESI-MS) was used to identify 1:1 stoichiometric complexes of Fe [HEDTA], Fe [EDTA] 1_ and Fe [DTPA] 2_, and the spectra showed that these Fe complexes were stable in solution. Furthermore, inductively coupled plasma mass spectrometry (ICP-MS) using an octopole reaction system (ORS) reduced polyatomic ion 40Ar16OR interference in the detection of 56Fe via the addition of either H2 or He to the ORS, with He at a flow rate 3.5mLmin_1 being the optimum collision gas. Finally, IC/ICP-MS was used for the separation and detection of Fe complexes with an eluent containing 30mM (NH4) 2HPO4 at pH 8.0, but only Fe [HEDTA], Fe [EDTA] 1_and Fe [DTPA] 2_were observed within 10 min with reasonable resolution. Detection limits in the range of 10-13mg L_1 were achieved using He as the collision gas. The proposed method was used for the determination of Fe species in soil solutions.

phase liquid chromatography with UV detection is of limited applicability in the separation and identification of carboxylic acids because of the column's poor separation efficiency and the non-selective nature of the UV detector. To address this issue, RP-LC with electrospray ionization mass spectrometry has been explored for the confirmation and determination of carboxylic acids in plant root exudates, with ESI-MS providing structural information, high selectivity, and high sensitivity. The separation of 10 carboxylic acids (pyruvic, lactic, malonic, maleic, fumaric, succinic, malic, tartaric, trans-aconitic, and citric acid) was performed on a C18 column using an eluent containing 0.1% (v/v) acetic acid within 10 min, where the acidic eluent not only suppressed the ionization of the carboxylic acids to be retained on the column, but was also compatible with ESI-MS detection. In addition, an additional standard was used to overcome the matrix effect. The results showed that peak areas correlated linearly with the concentration of carboxylic acids over the range 0.05-10mg/L. The detection limits of target acids (signal-to-noise S/N ratio of 3) ranged from 20 to 30lg/L. Finally, the proposed method was used for the confirmation and determination of low-molecular-weight carboxylic acids in plant root exudates, and provided a simple analytical procedure, including sample processing, fast separation, and high specificity and sensitivity.

Adsorption of cationic methylene blue and anionic orange II onto unmodified and surfactant-modified zeolites was studied using a batch equilibration method. The effects of equilibrium time, solution pH, and sorption temperature were examined. The results suggested that 2% sodium dodecyl benzenesulfonate (SDBS)- and 3% sodium dodecyl sulfate (SDS)-modified zeolites had higher adsorption capacities for methylene blue than the unmodified zeolite, while 2% cetylpyridinium bromide hexadecyl (CPB)- and 2% hexadecylammonium bromide (HDTMA)-modified zeolites were the best adsorbents for orange II. The adsorption conditions were optimized, and the mechanisms of adsorption are briefly discussed.

The reduction of 2, 4, 6-trinitrotoluene (TNT) in aqueous solution using nanoscale zero-valent iron (nZVI) was investigated. The results showed that the pseudo-first order reaction law fit the reduction of TNT. The measured apparent rate constant (Kobs) of TNT on nZVI (0.761 h−1) was 7.8-fold than on conventional iron powders (0.0979 h−1) at 303 K. The apparent activation energy (Ea) of nZVI reducing TNT was found to be 24.85 KJ/mol, which was decreased by 60% compared to employing conventional iron powders. The apparent rate constant ofTNTreduction on nZVI also can beimproved by an increase in nZVI concentration, reaction temperature and a decrease of pH.

Modified kaolinite clay with 25% (w/w) aluminium sulphate and unmodified kaolin were investigated as adsorbents to remove Pb (II) from aqueous solution. The results show that amount of Pb (II) adsorbed onto modified kaolin (20mg/g) was more than 4.5-fold than that adsorbed onto unmodified kaolin (4.2mg/g) under the optimized condition. In addition, the linear Langmuir and Freundlich models were used to describe equilibrium isotherm. It is observed that the data from both adsorbents fitted well to the Langmuir isotherm. The kinetic adsorption of modified and unmodified kaolinite clay fitted well to the pseudo-second-order model. Furthermore, both modified and unmodified kaolinite claywere characterized by X-ray diffraction, Fourier transform infrared (FT-IR) and scanning electron microscope (SEM). Finally, both modified and unmodified kaolinite clay were used to remove metal ions from real wastewater, and results show that higher amount of Pb (II) (the concentration reduced from178 to 27.5 mg/L) and other metal ions were removed by modified kaolinite clay compared with using unmodified adsorbent (the concentration reduced from 178 to 168 mg/L).

Kaolinite clay obtained from Longyan, Chinawas investigated to remove heavymetal ions fromwastewater. Thus,the present study includes the adsorption of Pb (II), Cd (II), Ni (II) and Cu (II) in aqueous solution on kaolinite clay through the process of adsorption under various conditions (with variable concentration ofmetal ion, amount of clay, pH and mixing time). Increasing pH favours the removal of metal ions till they are precipitated as the insoluble hydroxides. The uptake is rapid with maximumadsorption being observed within 30 min for Pb (II), Cd (II), Ni (II) and Cu (II). In addition, the results obtained fromadsorption isothermindicated that these data can be better fittedwith the Freundlich equation than the Langmuir equation. Furthermore, the XRD patterns confirmed that this kaolinite clay sample ismainly a mixture of kaolinite and illite clays. The SEMimages of samples showed irregular surface morphology. Finally, this kaolinite clay was used for removing metal ions fromrealwastewater such as Pb (II), where its concentration was reduced from 160.00 to 8.00mg/L.

This paper studied the effects of different carbon and nitrogen sources on the removal of iron impurities from kaolin using dissimilatory Fe (III) -reducing bacteria (DIRB). Iron impurities in the kaolin were removed using glucose, sucrose, food-sugar, maltose and soluble starch as different carbon sources with removal efficiencies in the order: monosaccharide>disaccharide>Npolysaccharide. More than 50% of the iron impurities were removed from kaolin with an increase of whiteness index from 61% to 82% at 5% (mass/mass) of food-sugar, indicating that food-sugar could alternatively be used as a bulk carbon source to reduce the operational cost of bioleaching. Addition of (NH4) 2SO4 to the bioleaching medium accelerated the bioleaching rate. The samples before and after bioleaching were examined by X-ray diffraction (XRD), X-ray fluorescence analysis (XRF) and scanning electron microscope (SEM). Iron was selectively leached from the kaolin without formation of a secondary mineral phase, structural changes were not observed but the crystallinity was improved.
