| 摘 要： | 采用UV/H2O2/草酸铁作为氧化剂氧化降解水中的聚丙烯酰胺(PAM)。研究了H2O2投加量、反应时间、n(Fe3+):n(草酸)对PAM降解的影响。试验结果表明,在室温25℃,n(Fe3+):n(草酸)=1:3,H2O2浓度为15 mmol.L-1,pH=3的条件下,光照120 min后,质量浓度为400 mg.L-1的PAM的去除率达到88.3%,与其它光氧化体系相比,去除效果较为明显。

| Abstract: | Using UV/H2O2/ferrioxalate for the oxidation degradation of polyacrylamide in water.The effects of concentration of H2O2,reaction time and the molar ratio of oxalate and ferric ion were studied.The experimental results showed that under the condition that the molar concentration of H2O2,Fe3+,ferrioxalate were 15 mmol·L-1,0.1 mmol·L-1,0.3 mmol·L-1,,the pH value was 3,the mass concentration of polyacrylamide in the water was 400 mg·L-1,the reaction time was 120mins,and the removal rate of polyacrylamide was 88.3%,which was much higher than other photo-oxidation systems. |
