The microwave-assisted acid-digestion for the determination of metals in coal by ICP-AES was investigated, especially focusing on the necessity of adding HF. By testing five certified reference materials, BCR-180, BCR-040, NIST-1632b, NIST-1632c, and SARM-20, it was found that the two-stage digestion without HF(HNO3+H2O2 was used)was very effective for the pretreatment of ICP-AES measurement. Both major metals(Al, Ca, Fe, and Mg)and minor or trace metals(Co, Cr, Cu, Mn, Ni, Pb, and Zn)in coal gave good recoveries for their certified or reference values. The possibility of 'HF-memory effect' was cancelled by the use of a set of vessels which had been never contacted with HF. Twenty-four Japanese standard coals(SS coals)were analyzed by the present method, and the concentrations of major metals measured by the present method provided very high accordance with those from the authentic JIS(Japanese Industrial Standard) method.

The demand for effective and inexpensive adsorbents is to increase in response to the widespread recognition of the deleterious health effects of arsenic exposure through drinking water. A novel adsorbent, aluminum-loaded Shirasu-zeolite P1(Al-SZP1), was prepared and employed for the adsorption and removal of arsenic(V)(As(V)ion from aqueous system. The process of adsorption follows first-order kinetics and the adsorption behavior is fitted with a Freundlich isotherm. The adsorption of As(V)is slightly dependent on the initial pH over a wide range(3-10). Al-SZP1 was found with a high As(V)adsorption ability, equivalent to that of activated alumina, and seems to be especially suitable for removal of As(V)in low concentration. The addition of arsenite, chloride, nitrate, sulfate, chromate, and acetate ions hardly affected the As(V)adsorption, whereas the coexisting phosphate greatly interfered with the adsorption. The adsorption mechanism is supposed as a ligand-exchange process between As(V)ions and the hydroxide groups present on the surface of Al-SZP1. The adsorbed As(V)ions were desorbed effectively by a 40mM NaOH solution. Continuous operation was demonstrated in a column packed with Al-SZP1. The feasibility of this technique to practical utilization was also assessed by adsorption/desorption multiple cycles with in situ desorption/regeneration operation.

A novel method for the removal of inorganic arsenic(Ⅲ) (As(Ⅲ)), monomethylarsonate(MMA), and dimethylarsinate(DMA) from aqueous media, was proposed and investigated. This method involves the combined use of TiO2-photocatalyst and an adsorbent, which has a high ability of As(Ⅴ) adsorption, under photo-irradiation. When an aqueous solution of As(Ⅲ) was stirred and irradiated by sunlight or xenon lamp in the presence of TiO2 suspension, the oxidation of As(Ⅲ) into As(Ⅴ) was effectively attained. By use of the same photocatalytic reaction, MMA and DMA were also degraded into As(Ⅴ), while the total organic carbon(TOC) in the aqueous phase was decreased. When an aqueous solution of As(Ⅲ) was stirred with a mixed suspension of TiO2 and an adsorbent for As(Ⅴ)(activated alumina) under sunlight irradiation, the arsenic removal reached89%after 24h. By use of the same photocatalyst-adsorbent system, 98% of MMA and97%of DMA were removed. The mechanism of the removal of arsenic species by the photocatalyst-adsorbent system was discussed.
