| 摘 要： | 水溶性染料活性艳红（Ｘ－３Ｂ）在铁盐与腐植酸共存下，光解脱色效果明显，结果表明在ＰＨ＝３，１．０＊１０＾－５ｍｏｌ／ＬＦｅ（Ⅲ）与０．５ｇ／Ｌ腐植酸的条件下，２０ｍｇ／Ｌ活性艳红溶液的脱色率为７１．４％。染料溶的ＰＨ值，Ｆｅ（Ⅲ），腐植酸的浓度以及当杰溶液的初始浓度均对染料的脱色有影响。

| Abstract: | The test of decoloration of the dyes C.I.reactive 2 was conducted in the system UV/Fe()-Humic acid. The results showed that under the conditions of pH=3, 0.5mg/L humic acid(HA) and 1.010-4mol/L Fe(), the decoloration efficiency of dye solution (20mg/L) was 71.4%. The effect of pH, the concentration of Fe(),HA, and initial concentration of the dye solution on the decoloration of dye were examined in this study. |
