英文摘要Diphenylarsinic acid (DPAA) is a phenyl arsenic compound derived from chemical warfare weapons. Macroscopic and microscopic work on DPAA sorption will provide useful information in predicting the partitioning and mobility of DPAA in the soil-water environment. Here, batch experiments and extended X-ray absorption fine structure (EXAFS) spectroscopy were used to investigate the sorption mechanisms of DPAA. The DPAA sorption data from 11 soil types was found to fit the Freundlich equation, and the sorption capacity, K-f, was significantly and positively correlated with oxalate-extractable Fe2O3. The K-f values of eight of the 11 untreated soils (1.51-113.04) significantly decreased upon removal of amorphous metal (hydr)oxides (0.51-13.37). When both amorphous and crystalline metal (hydr)oxides were removed from the untreated soils, the K-f values either decreased or slightly increased (0.65-3.09). Subsequent removal of soil organic matter from these amorphous and crystalline metal (hydr)oxide-depleted samples led to further decreases in K-f to 0.02-1.38, with only one exception (Sulfic Aquic-Orthic Halosols). These findings strongly suggest that ligand exchange reactions with amorphous metal (hydr)oxides contribute most to DPAA sorption on soils. EXAFS data provide further evidence that DPAA primarily formed bidentate binuclear (C-2) and monodentate mononuclear (V-1) coring-sharing complexes with As-Fe distances of 3.34 and 3.66 angstrom, respectively, on Fe (hydr)oxides. Comparison of these results with earlier studies suggests that C-2 and V-1 complexes of DPAA may be favored under low and high surface coverages, respectively, with the formation of V-1 bonds possibly conserving the sorption sites or decreasing the steric hindrance derived from phenyl substituents.
