摘要
将吸附与光催化降解污染物协同效应的理念引入处理有机污染物的研究当中,将壳聚糖与纳米二氧化钛作为原料,制取成负载纳米二氧化钛的壳聚糖多孔材料,并研究其浓度、光催化时间、pH等因素对模拟废水活性艳红吸附的影响。实验结果表明:当纳米二氧化钛与壳聚糖投加配比为1∶2、溶液pH值=6、反应温度为20~40℃、光催化时间为90 min时,壳聚糖负载纳米二氧化钛对活性艳红模拟废水的吸附能力达到74.2%。
In this paper, the concept of synergistic effect of adsorption and photocatalytic degradation of pollutants was introduced into the study of organic pollutants.Chitosan and nano titanium dioxide were used as raw materials to prepare Chitosan porous material loaded with nano titanium dioxide and to study the influence of concentration, the photocatalytic time, pH and other factors on reactive brilliant red.The experimental results show that when the ratio of nano titanium dioxide and chitosan is 1：2, pH=6, the reaction temperature is 20- 40 ℃ and the photocatalytic time is 90min, the adsorption capacity of chitosan supported nano titanium dioxide on reactive brilliant red reached 74.2 %.
