研究了羧甲基壳聚糖与无机絮凝剂复配使用净化海水的效果。羧甲基壳聚糖分别与三种常用无机絮凝剂(AlCl3、FeCl3和聚合铝铁)的复合絮凝效果表明,其中FeCl3与羧甲基壳聚糖对海水的复合絮凝效果较好。通过正交试验考察了羧甲基壳聚糖与FeCl3的复配比例及应用条件,结果表明,羧甲基壳聚糖氯化铁复合絮凝剂具有投加量少,絮凝效果好,有效去除海水中的污染物等特点。
The effect of using seawater with carboxymethyl chitosan and inorganic flocculant was studied. The complex flocculation effect of carboxymethyl chitosan and three common inorganic flocculants (AlCl3, FeCl3 and polymerized aluminum and iron respectively) showed that the flocculation effect of FeCl3 and carboxymethyl chitosan on seawater was better. The orthogonal experiment was used to investigate the compounding ratio and application conditions of carboxymethyl chitosan and FeCl3. The results showed that carboxymethyl chitosan ferric chloride complex flocculant had the advantages of less dosage, good flocculation effect and effective removal of seawater In the characteristics of pollutants.
