摘　　要：以曙红Y染料为研究对象,对日光/草酸铁/过氧化氢组成的改进Fenton试剂处理曙红Y染料废水进行了研究,探讨了反应时间、pH、过氧化氢投加量、草酸钠以及硫酸铁用量对脱色率的影响。并确定其最佳条件为:溶液pH值为3左右,草酸钠1 mL,硫酸铁2 mL,H2O20.5 mL,在此条件下光照30 min曙红Y溶液的脱色率达99.80%。In this paper, a feasible research on photodegradation of Eosin Y under solar irradiation by ferrioxalate/hydrogen peroxide was carried out . The effect of reaction time, pH value, and the usage 4 of H2O2, sodium oxalate and ferric sulfate were investigated. The optimal conditions of decolouration efficiency were determined as following： pH=3, the usage of H2O2, sodium oxalate and ferric sulfate were 0. 5 mL,1 mL and 2 mL,respectively. Under the conditions, with sunny irradiation for 30 min the decolouration efficiency was about 99.80 %.
