摘　　要：研究了Fe(III)-草酸配合物在可见光及太阳光照射下,对氯苯酚的光解降解作用。结果表明,在pH=4.0、Fe(III)/H2C2O4=0.040mmol/L/1.44mmol/L(草酸分3次加入)、光照3h的条件下,20mg/L的对氯苯酚的降解率为89.80%。溶液pH值、铁与草酸浓度比和苯酚浓度均对降解效果产生影响。The experiment of photochemical degradation of the p-chlorophenaol was conducted in aqueous solution containing Fe(Ⅲ)-oxalate complex irradiated with visible light and sunlight.The result showed that under the condition pH=4.0,Fe(Ⅲ)/H2C2O4=0.040mmol/L/1.44mmol/L(oxalic acid was divide into trisection and add in),the degradation rate of 20mg/L p-chlorophenol was 89.8% in 3h sun light irradiation.It is found that pH,concentration ratio of Fe(Ⅲ) to oxalate and initial concentration of the p-chlorophenol have some effect on the degradation rater.
