| 摘 要： | 利用蒙脱石与壳聚糖2种天然材料,将壳聚糖固载于蒙脱石表面作为絮凝剂,用于处理养殖水体中重金属铜。试验结果表明,在蒙脱石负载壳聚糖投加量为0.8‰～1.0‰、絮凝吸附反应时间为16 min、溶液pH值为6时,对铜的去除效果最佳;与单一材料相比较,制备的新型絮凝剂对铜的去除能力强,且用量少。

| Abstract: | The chitosan immobilized on montmorillonite surface as flocculants was applied to treat the copper in aquaculture water by means of two natural materials montmorillonite and chitosan.The results showed that the copper removal efficiency was optimum,under dosage of montmorillonite supported chitosan 0.8‰ to 1.0‰;when adsorption time of flocculation was 16 min and pH was about 6,it had the optimum remove effect.The new type of flocculant had more powerful and economic removal of copper,compared with a single material. |
