| 摘 要： | 采用多种简单有机配体制备了系列铁（Ⅲ）配合物.通过循环伏安法对合成的配合物进行了分析,研究了该系列配合物对双氧水降解聚丙烯酰胺的催化性能.结果表明,配体对配合物的催化作用影响较大,磺基水杨酸-铁（Ⅲ）（3：1）对双氧水降解聚丙烯酰胺的催化性能最好;在优选条件下该氧化体系可以将相对分子质量为500万的聚丙烯酰胺降解至442左右,使黏度大大降低.

| Abstract: | Fe（Ⅲ） complexes were prepared with simple organic ligands and Fe（ Ⅲ ）. These complexes were characterized by CV. These complexes were used as catalysts in the H202 oxidation degradation of polyacrylamide gel. The experimental results showed： the ligands ef-fect the catalysis efficiency, and the most effective one is the composed by sulphosalieylic acid and Fe（ Ⅲ）, with the ratio of 3 ： 1. Under the optimum conditions, the molecular weight of polyacrylamide was decreased from 5 million to about 442, and the viscosity was de-creased greatly. |
