The removal of color and chemical oxygen demand (COD) from simulated dye wastewater containing Acid Orange II was experimentally investigated using coagulation-electrooxidation. Two kinds of coagulation methods, ferrous-mediated coagulation and electrocoagulation were tested as pretreatment. The electrooxidation was carried out in a cell with a three-phase three-dimensional electrode using granular activated carbon as particle electrodes. Particular attention was paid to probe the effect of cell voltage, airflow rate, solution conductivity and treatment time on the electrochemical treatment efficiency. The experimental results showed that the coagulation-electrooxidation process could efficiently remove the color and the COD from the simulated dye wastewater. The overall COD and color removal efficiencies reached as high as 99% and 87%, respectively, by ferrous coagulation (molar rate of Fe(II)/dye: 0.5) and 30-min electrolysis (cell voltage: 20.0V and airflow: 0.1m3 h-1).

A platinised TiO2/ITO film, Pt-TiO2/ITO, was prepared by a dip-coating and subsequent photodeposition procedure. Compared with bare TiO2/ITO film, Pt-TiO2/ITO film not only possesses a relative high photocatalytic activity but also shows a rather non-photocatalytic activity towards HCOOH degradation at room temperature and atmosphere pressure. The non-photocatalytic effect of platinised TiO2 was partly responsible for degradation of formic acid in the photocatalytic process. The non-photocatalytic activity of Pt-TiO2/ITO film is very dependent on its preparation method.

A dimethoate-degrading enzyme from Aspergillus niger ZHY256 was purified to homogeneity with a specific activity of 227.6 U/mg of protein. The molecular mass of the purified enzyme was estimated to be 66 kDa by gel filtration and 67 kDa by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The isoelectric point was found to be 5.4, and the enzyme activity was optimal at 50℃ and pH 7.0. The activity was inhibited by most of the metal ions and reagents, while it was induced by Cu21. The Michaelis constant (Km) and Vmax for dimethoate were 1.25 mM and 292 mmol min21 mg of protein21, respectively.

The aim of this paper is to report the recent laboratory work on the synthesis of novel Ru(Ⅱ) polypyridine complexes and the studies of their interaction with DNA. The first part describes the syntheses and crystal structures of several novel polypyridine ligands containing imidazole or Schiff base moiety and their Ru(Ⅱ) complexes. The second part focuses on the influences of the shape, size and substitute groups of intercalative ligands and co-ligands on the binding modes, intensities and enantioselectivities of the complexes to DNA. The interactions of Ru(Ⅱ) complexes to different native DNAs are also compared. Certain regularity between the selection of a particular binding mode and the structure of complexes and:or DNA was observed. The final part of the paper reports the preliminary studies on a new DNA-mediated luminescence quenching assembly. The experimental results seem to support the notion that the p-stacked bases of DNA polymer maybe offer a pathway for electron transfer.

2-(2-Chlorophenyl)imidazo[4,5-f ]1,10-phenanthroline (CIP) or 2-(2-nitrophenyl)imidazo[4,5-f ]1,10-phenanthroline (NIP) and their complexes [Ru(bpy)2(CIP)]21 and [Ru(bpy)2(NIP)]21 (bpy=2,29-bipyridine) have been synthesized and characterized. The binding of the two complexes to calf thymus DNA has been investigated with spectrophotometric methods and viscosity measurements. The experimental results indicate that the two complexes bind to DNA through a partial intercalative mode that is different from the bonding mode for their parent compound, [Ru(bpy)2(PIP)]21 (PIP=2-phenylimidazo[4, 5-f ]1, 10-phenanthroline). The crystal structure of [Ru(bpy)2(CIP)]-[ClO4]2?2H2O was determined by X-ray diffraction analysis; the imidazo[4, 5-f ]1, 10-phenanthroline moiety is not coplanar with the 2-chlorophenyl ring, having a dihedral angle of 44.58 in the CIP.

Pd-TiO2/ITO films were prepared by a dip-coating and subsequent photo-deposition procedure. The Pd-TiO2/ITO film was well characterized by X-ray diffraction, scanning electron microscope and open circuit voltage. It was found that the Pd-TiO2/ITO film not only possessed higher photocatalytic and photoelectrocatalytic activities, compared with bared TiO2/ITO film, but also showed a certain non-photocatalytic activity towards HCOOH degradation at room temperature and atmosphere pressure. This is the first report about versatile catalytic activities of Pd-TiO2 film.

【期刊论文】The enhanced PC and PEC oxidation of formic acid in aqueous solution using a Cu–TiO2/ITO film

The photocatalytic (PC) and photoelectrocatalytic (PEC) activity of Cu-TiO2/ITO films for degrading formic acid in aqueous solution was investigated in this study. Compared with a TiO2/ITO film, the degradation efficiency of formic acid on the Cu-TiO2 films increased markedly in both the PC and PEC oxidation processes. However, it was found that the photodeposited Cu metal on the Cu-TiO2 films could electrochemically dissolute during the PEC reaction, while an electrical bias with the voltage higher than 1.48V was applied. It is believed this is a common problem occurred for several metals deposition on the TiO2 films, which results in a poor stability of the metal-deposited TiO2 electrode in PEC processes. To improve the stability of the Cu-TiO2 electrode, an alternative process between PC and PEC reactions was investigated. It was found that the dissolute Cu metal during the PEC process was re-deposited on the Cu-TiO2 film again during the PC process. The experiments with repeated runs demonstrated that this alternative process could not only overcome the loss of Cu, but also enhance the PEC oxidation efficiency of the Cu-TiO2 films.

The removal of chemical oxygen demand (COD) from wastewater-containing phenol was investigated using threephase three-dimensional electrode reactor. Special attention was paid to experimentally probe the performance of the reactor in COD removal in the process of repeated batch runs. The experimental results showed that the reactor could remove COD from phenol-containing wastewater much more efficiently than both granulated activated carbon (GAC) adsorption bed and conventional three-dimensional electrode. For 200th batch run, the three-phase three-dimensional electrode reactor with an airflow of 5 1min-1 and a cell voltage of 30 V could remove 1350 ppm COD from the wastewater in 30 min while conventional three-dimensional electrode reactor with a same cell voltage and GAC adsorption bed with a same airflow only could remove 610 and 1000 ppm, respectively, at the same reaction duration. Although it was found that COD removal decreased with increasing repeated batch runs in our experimental range, due to adsorption saturation of GAC and electrode passivation, the extent of decrease for the three-phase three-dimensional electrode is much less than those for conventional three-dimensional electrodes and GAC adsorption beds. The passivated reactor could be partly re-activated by electrolysis in the presence of MnO2.

Ag-TiO2 composite film was supported on indium–tin oxide glass (ITO) by a dip-coating and subsequent photodeposition procedure. The composite film was characterised by UV-Vis diffuse reflectance spectra, X-ray reflection diffraction (XRD) spectra, scanning electron microscope (SEM) and photoelectrochemical measurement. Itwas used as a photoanode in a two-compartment photoelectrochemical cell to investigate the feasibility of a hybrid technology of Ag deposition combined with the application of an external electric field. The experimental results show that the combination has an apparent additive effect with respect to suppressing the recombination between the photogenerated charge carriers and enhancing the photoelectrocatalytic (PEC) oxidation of formic acid. A primary approach to a pulse PEC technology presents the possibility that the Ag-TiO2/ITO film electrode is performed at an anodic bias over the oxidation potential of the deposited Ag.

【期刊论文】Improving photocatalytic activity of Cu-loaded TiO2 film using a pulse anodic bias

The application of a small anodic bias can promote the photocatalytic oxidation of formic acid on Cu-TiO2 film. However, the photocatalytic activity was not stable at higher anodic biases or in the process of repeated use due to the electrochemical oxidation of Cu. A new photocatalytic technology with a pulse anodic bias was proposed to tackle the deficiency of the Cu-TiO2 film. It was found that the photocatalytic technology could not only overcome the Cu oxidation but also increased the photocatalytic activity of the Cu-TiO2 film.
