摘　　要：研究了紫外光 (U V) /草酸铁络合物对对硫磷的光解作用 ,结果表明 ,UV /草酸铁络合物能快速有效地光解对硫磷 ,且较 U V/ Ti O2 的光解效果好。对硫磷光解率随着其初始浓度的增加而降低 ;p H为 3～ 5时其光解速率最快 ;[Fe( ) ]与 [OX2 - ]之比 (OX2 -代表草酸根 )和溶液中的溶解氧对其光解有显著影响。A study on photodegradation of parathion by UV/ferric oxalate complexes has been carried out. The results show that parathion can be degraded rapidly and efficiently by UV/ferric oxalate complexes, and better than by UV/TiO 2. The degradation rate of parathion decreases with its initial concentration increasing and is the highest at solution pH 3~5. The concentration ration of Fe(Ⅲ)to OX 2- (oxalic group) and DO concentration have significant effects on parathion degradation.
