摘要：Effects of several key influencing factors of environmental photochemistry, including iron, nitrate and dissolved organic matter (DOM), on the photochlorination of bisphenol A (BPA) were investigated. Iron promoted the formation of chlorinated BPA, but the rate decreased with increasing pH. This result was consistent with the results of laser flash photolysis, which showed that high pH decreased the formation of reactive chlorine species (chlorine radical, Cl(center dot)/Cl(2)(center dot-)). Nitrate ion and citric acid, which was selected as an analogue of DOM, inhibited the chlorination of BPA separately. The results presented in this paper are helpful to get some idea of the degree of photochemical chlorination in aqueous environment.
