摘要：The degradation of sulfamethoxazole (SMX) was investigated under the sono-catalytic ozonation process over magnetic suspension. The effects of various operating conditions were investigated, including initial pH value, catalyst dosage, and power density. The results indicated that the degradation of SMX followed a pseudo-first-order kinetic model under different operating conditions. The removal rate increased with the increase of pH, but it decreased when the catalyst dosage or power density exceeded a certain value. The removal rate was inhibited in the presence of tert-butyl alcohol, isopropanol or NaF. After 20 min treatment, the COD removal reached 57.5%, the acute toxicity to Daphnia magna largely decreased, and the biodegradability (BOD5/COD ratio) increased from 0.02 to 0.41. COD was almost completely removed when the reaction time was extended to 120 min.

2.标题：Degradation of bisphenol A in aqueous solution by a novel electro/Fe3+/peroxydisulfate process作者：Lin, Heng; Wu, Jie; Zhang, Hui

摘要： The removal of bisphenol A (BPA) by a novel "electro/Fe3+/peroxydisulfate" process is reported in this study. The effects of initial pH, electrolyte concentration, Fe3+ concentration, peroxydisulfate (PDS) concentration and current density were investigated. The results indicated that the removal efficiency of BPA declined with the increase of initial pH and electrolyte concentration, but increased with an increase of Fe3+ concentration and current density. The BPA degradation efficiency was improved significantly when the PDS concentration was increased from 1 to 10 mM, but further PDS increase had little effect. BPA was almost completely removed after 60 min reaction and a TOC removal efficiency of 94.3% was achieved when the reaction time was extended to 120 min.
