1、安徽工程大学毕业设计（论文）壳聚糖负载硅藻土对直接大红溶液吸附性能研究姓名班级学号（某某大学某某学院地点邮编）摘要本文研究了壳聚糖负载硅藻土对模拟印染废水直接大红溶液的吸附性能。分别探讨了壳聚糖负载硅藻土量、染料浓度、介质的pH值、吸附温度及吸附时间对吸附性能的影响，最终得到了壳聚糖负载硅藻土对模拟染料废水直接大红溶液的最佳吸附条件。结果表明：对于一定浓度的直接大红溶液，随着壳聚糖负载硅藻土用量的增加，对直接大红溶液的吸附量逐渐增强，在负载硅藻土用量为0.03g左右效果较好；介质的pH值在3的条件下，负载硅藻土对直接大红吸附性能较
2、好；随着吸附时间的增长，吸附量不断增大最后达到平衡值，在180min左右达到平衡；温度对吸附性能影响较小，在45℃时吸附性能相对较好；负载硅藻土的吸附量随染料浓度的增大逐渐增大。结论：壳聚糖负载硅藻土用量在0.03g左右，pH值在3条件下，时间在180min左右，温度在45℃时有很好的吸附性能。吸附量分别为：34.55mg/g，39.25mg/g，32.24mg/g，34.43mg/g。关键词：壳聚糖；硅藻土；壳聚糖负载硅藻土；直接大红溶液；吸附；分光光度法V安徽工程大学毕业设计（论文）Thestudyoftheadsorptio
