2、都在105min左右达到平衡，温度对吸附性能影响较小，在25℃时吸附性能相对较好；负载蒙脱土的吸附量随染料浓度的增大逐渐增大,本文的吸附符合Langmuir和Freundlich吸附模型。结论：壳聚糖负载蒙脱土用量在0.06g左右，pH值在2-5条件下，时间在105min左右，温度在25℃时有很好的吸附性能。关键词：壳聚糖；蒙脱土；壳聚糖负载蒙脱土；活性翠蓝溶液；吸附；分光光度法V某某大学毕业设计（论文）ThestudyoftheadsorptionbehaviorofChitosanloadedmontmorilloniteforReactiveturquoisebluesolution
