| 摘 要： | 染料在工业中被越来越广泛地使用,其产生的废水已经成为目前较为难处理的工业废水之一.以壳聚糖为改性剂,对资源丰富的天然膨润土进行有机改性,制得一种新型水处理剂--壳聚糖改性膨润土.采用物理吸附法对酸性大红染料废水进行处理,考查了pH值、搅拌时间、投土量、离心时间4个因素的影响,确定了最佳处理工艺条件:pH值4、搅拌6 min、投土量14 g/L、离心17 min.此时处理效果最佳,脱色率可达97%.此外,通过对原土和壳聚糖改性膨润土进行的比表面积、红外光谱和扫描电镜等表征测定分析可知,壳聚糖的加入并没有改变膨润土的基本框架,只是增大了膨润土的比表面积,从而提高吸附性能.

| Abstract: | Dyes are widely used in industries and their removal from industrial wastewater poses an important issue.A new type of treating agent, chitosan modified bentonite, was prepared.Bentonite had been proven to be a promising material for the removal of contaminants from wastewater, which belongs to the 2:1 clay family.Not only bentonite is abundant in nature, but also it is really an efficient and economic adsorbent for adsorption of pollutants including dyes, oil and heavy-metals.Conventional methods for the r... |
