摘要
壳聚糖由于其优良的吸附、螯合性能在水质净化领域已显示出了其广泛的应用前景。本课题主要是对壳聚糖处理污水中的Pb^(2+)优化条件研究。分别在不同壳聚糖用量、反应时间、反应温度、反应pH值等条件下,进行壳聚糖吸附Pb^(2+)反应,然后测定吸附后的Pb^(2+)浓度。得出壳聚糖吸附铅离子反应优化条件。进行壳聚糖的解吸附实验,验证壳聚糖的再生性能。
Chitosan due to its excellent adsorption, and chelating ability in the field of water purification so it has shown its broad application prospects. This article mainly studies the best conditions of chitosan in the treatment of Pb2＋ in sewage. Contrast the difference of concentration change under various conditions, analysis the amount of chitosan, reaction time, reaction temperature, pH effect on the sewage treatment, respectively, and derived optimum adsorption conditions. Chitosan desorption experiments was to verify the performance of chitosan regeneration.
