- W3148090596 abstract "As one of the most toxic heavy metals, the oxidation of inorganic arsenic has drawn great attention among environmental scientists. However, little has been reported on the solar photochemical behavior of arsenic species on top-soil. In the present work, the influencing factors(p H, relative humidity(RH), humic acid(HA), trisodium citrate, and additional iron ions) and the contributions of reactive oxygen species(ROS, mainly HOUand HO2U/O2U-) to photooxidation of As(Ⅲ) to As(Ⅴ) on kaolinite surfaces under UV irradiation(λ = 365 nm)were investigated. Results showed that lower p H facilitated photooxidation, and the photooxidation efficiency increased with the increase of RH and trisodium citrate.Promotion or inhibition of As(Ⅲ) photooxidation by HA was observed at low or high dosages, respectively. Additional iron ions greatly promoted the photooxidation, but excessive amounts of Fe2+competed with As(Ⅲ) for oxidation by ROS. Experiments on scavengers indicated that the HOUradical was the predominant oxidant in this system.Experiments on actual soil surfaces proved the occurrence of As(Ⅲ) photooxidation in real topsoil. This work demonstrates that the photooxidation process of As(Ⅲ) on the soil surface should be taken into account when studying the fate of arsenic in natural soil newly polluted with acidic wastewater containing As(Ⅲ)." @default.
