Abstract

Abstract:

Magnetic chitosan(MCS) was synthetized by inverse suspension polymerization method. The performance of MCS was investigated through FTIR and SEM. By adsorption and coagulation experiments, the best removal efficiency of small molecular salicylic acid by adsorbent MCS was 74.6%, which was higher than that of humic acid (16.9%). The removal efficiency of macro molecular humic acid by coagulant aluminum sulfate was 67.4%, which was higher than that of salicylic acid(15.2%). The removal efficiency of salicylic acid and humic acid were improved by means of combined application, and the removal efficiency of humic acid and salicylic were 75.5% and 78.7%.

Key words: magnetic chitosan, coagulant, humic acid, salicylic acid

摘要：

通过反相悬浮交联法合成了磁性壳聚糖（MCS），并通过FTIR、SEM对MCS进行了表征。通过吸附和混凝实验，得出吸附剂磁性壳聚糖对小分子水杨酸的最佳去除率为74.6%，明显高于对腐殖酸的去除率（16.9%）；混凝剂Al（SO₄）₃对大分子腐殖酸的去除率为67.4%，高于对水杨酸的去除率（15.2%）；磁性壳聚糖-混凝联合工艺能提高水处理材料去除有机物的效率，对腐殖酸和水杨酸的去除率分别为75.5%和78.7%。
