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 removal of dyes from wastewater include adsorption to solid substrates, chemical coagulation, oxidation, filtration and biological treatment. Adsorption is one of the easiest and most effective techniques to remove dilute pollutants among conventional methods. In this paper, the enffluent factors of absorption of acid scarlet in dyeing wastewater on modified bentonite are investigated, including pH value, ratio of modified bentonite mass to wastewater, mixing time and centrifugating time to obtain optimal treatment conditions. The removal rate of chromacity is found to be 97% under the conditions of 30 g/L ratio of modified bentonite mass to wastewater, pH value of 4, 6 min of mixing time and 17 min of centrifugating time. In addition, for better explanation of these results, the natural bentonite and chitosan modified bentonite were critically examined in specific surface area, and with SEM and IR analyses. Results show that structure of bentonite is not changed by adding chitosan, except an increased specific surface area and improved adsorptive capability. It is concluded that chitosan modified bentonite has a promising application in removing acid scarlet from wastewater using adsorption methods., authors=null, authorsList=null, authorCompany=null,

articleAbstract=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。, authors=邵红,邵爽,王海冰,程慧, authorsList=邵红;邵爽;王海冰;程慧, authorCompany=沈阳化工学院 环境与生物工程学院,
