通过对分子筛载体的筛选,确定在可见光光催化降解橙Ⅱ(简称Org Ⅱ)时NaY分子筛为Fe~(2+)的理想载体,并以负载Fe~(2+)的NaY分子筛(简称FeY)为催化剂降解染料橙Ⅱ,研究了H_2O_2的量、催化剂的量、pH等因素对降解效果的影响及橙Ⅱ降解和H_2O_2的分解情况,结果表明在选定的Org Ⅱ/FeY/H_20_2可见光照射下,反应210 rain橙Ⅱ的脱色率达100%,TOC去除率达63%,催化剂在循环使用至少7次其催化活性基本不变.

Fe（ Ⅱ ） supported on different types of zeolites as catalysts for heterogeneous photodegradation were prepared, and confirmed NaY zeolite as the perfect support of Fe （ Ⅱ） for degradating orange Ⅱ . The effects of concentration of H2O2 and catalyst, initial pH were investigated. The results showed that Org Ⅱ could be efficiently degradated by chosen Org Ⅱ/FeY/H2O2 system under visible irradiation with 100% decolorization and 63% TOC removal after 210min reaction. After used 7 recycles the cata...
