摘要
进行了铁-草酸盐络合物在紫外光照射下，对水溶性染料（活性艳红X－3B）的光解脱色研究。结果表明，在pH＝4，Fe（Ⅲ）／C2O＝20μmol·L-1／240μmol·L－1的条件下，铁-草酸盐络合物／UV对20mg／L染料的混合溶液的脱色率为43．1％，有一定的脱色效果。溶液的pH值、铁与草酸盐的浓度比（Fe／OX）和染料物初始浓度均会对染料脱色速率有所影响。
The test of photo chemical discoloration of the dye, C. I. reactive red 2, was conducted in aqucous solutions containing Fe (Ⅲ) -oxalate complexes irradiated with UV light. The result showed that under the condition of pH4, Fe (Ⅲ) /C2O = 20 μmol L-1/240 μmol L-1, the disco1oration rate of mixed solution entailing 20 mg/L dye was 43. 1 %. It is found that pH, concentration ratio of Fe (Ⅲ) to oxalate (Fe/Ox) and initial concentration of the dye solution have effects on the discoloration rate.
