吸附亚甲基蓝毕业论文

您好，催化剂用量对光降解的影响主要有两个方面： 1、催化剂用量越多，光降解的效率就越高。因为催化剂能够加速光降解反应，使反应速率更快，从而提高光降解的效率。 2、催化剂用量越多，光降解的产物也会发生变化。因为催化剂能够改变反应的过程，从而改变光降解的产物。 因此，催化剂用量对光降解的影响是非常显著的，应根据实际情况选择合适的催化剂用量，以获得最佳的光降解效果。

亚甲基蓝溶液浓度对二氧化钛吸附性能的影响：大多数固体对次甲基蓝的吸附都是单分子层吸附，平衡后浓度太低时吸附不能达到饱和，浓度太高则会发生多分子吸附。0.2%为前人实验的最佳值。

在大多数固体上，次甲基蓝吸附都是单分子层，即符合朗格缪尔型吸附。但当原始溶液浓度较高时，会出现多分子层吸附，而如果吸附平衡后溶液的浓度过低。

则吸附又不能达到饱和，因此，原始溶液的浓度以及吸附平衡后的溶液浓度都应选在适当的范围内。本实验原始溶液浓度为0.2%左右，平衡溶液浓度不小于0.1%。

制备方法

1、由N,N-二甲基苯胺进行亚硝化，经还原生成对氨基二甲基苯胺，再用重铬酸钠、硫代硫酸钠进行氧化、硫化及缩合，然后用氯化锌成盐、盐析、过滤及干燥即得成品。

2、在工业次甲基蓝（碱性湖蓝BB）10kg中加入100kg纯水，边搅拌边通蒸汽加热至80～90℃，使之溶解。然后用30min时间缓慢加入20%的碳酸钠热溶液7.5kg，继续搅拌10min，静置半小时后，将溶液加热，温度不超过90℃，趁热过滤，在清亮滤液中加入3kg 1∶1的盐酸，搅拌均匀后，冷却结晶，结晶完全后，离心甩干，于40～50℃干燥，即得成品。
