采用双氧水氧化降解聚丙烯酰胺，研究了羟肟酸-铁(Ⅲ)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，苯甲羟肟酸-铁(Ⅲ)（2∶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分子量为500万的聚丙烯酰胺降解至317左右，使黏度大大降低。

H2O2 was used for the oxidation degradation of polyacrylamide gel, and the catalysis of hydroxamic acid-Fe( Ⅲ ) complexes was studied. The experimental results showed:the ligands effect, the catalysis efficiency and the most effective one was the compose by benzyl hydroxamic acid and Fe(Ⅲ) with the ratio of 2∶1. Under the optimum conditions, the molecular weight of polyacrylamide was decreased from 3 million to about 317, and the viscosity was decreased greatly.
