非均相Fenton反应催化降解聚丙烯酰胺

Degradation of Polyacrylamide over Heterogeneous Fenton Catalyst

研究了载体类型、活性组分负载方法和负载量和反应条件对催化剂活性的影响。结果表明,以NaY为载体,采用微波法制备氧化铁负载量为5%(质量分数)的催化剂,在反应时间1 h,反应温度30℃,催化剂加入量5 g/L,H2O2用量7 mL/L的条件下,对浓度为200 mg/L的聚丙烯酰胺溶液的降解率可达86.63%。

The effects catalysts were investigated. of support, preparation The results showed that and using NaY zeolite as support exhibits superior solution of 200 mg/L under the conditions of time amount of 7 mL/L. method, iron loading and reaction conditions on degradation activity of the catalyst with 5 % （w） iron oxide prepared via microwave irradiation activity, which can achieve a degradation ratio of 86.63% for PAM of 1 h, temperature of 30 %, catalyst amount of 5 g/L and H202
