以H2O2/草酸铁络合物作光氧化剂，利用太阳光对水溶液中的直接耐酸大红进行了光氧化降解试验研究。结果表明，在日光照射下，H2O2/草酸铁络合物能使溶液中直接耐酸大红迅速光解，晴天光照15 min或阴天光照30～40 min，溶液(直接耐酸大红的质量浓度为50 mg/L)可褪至无色；溶液的初始pH对染料光解有显著影响，pH为2～4时光解效果最佳；提高H2O2浓度可以提高光解速率，但H2O2的利用率会降低。

The photooxidative degradation of Direct Fast Scarlet dyes in aqueous solution under solar irradiation by H2O2/ferrioxalate complexes has been studied.The results indicate that the dyes in the solution can be rapidly degraded by the process.The dye solution (50 mg/L of mass concentration)is completely decolored after15 min of irradiation under sunny sky or 30～40 min under overcast sky.The initial pH of thesolution has significant effect on the photolysis.The efficiency of photolysis is highest at pH 2～4.The destruction rate of the dyes is increased with increasing concentration of H2O2,but the utilization efficiency of H2O2 is decreased at high level of H2O2.
