摘要
通过表面引发接枝聚合将甲基丙烯酸接枝聚合到活性炭表面,用于处理高氯酸铵污染水的研究。结果表明,改性活性炭吸水率明显提高,高氯酸铵吸附量2. 28 mg/g,吸附平衡时间10 min。与活性炭相比,吸附量提高了2. 2倍,吸附平衡时间降低了60%。
Methacrylic acid was grafted onto the surface of activated carbon by surface initiating graft polymerization,and then applied to the treatment of water contaminated by ammonium perchlorate. The results showed that the water absorption rate of modified activated carbon increased significantly,the adsorption capacity of ammonium perchlorate was 2. 28 mg/g,and the adsorption equilibrium time was 10 min. Compared with activated carbon,the adsorption capacity increased by 2. 2 times and the adsorption equilibrium time decreased by 60%.
