| 摘 要： | 通过溶胶-凝胶法制备纳米TiO2,并将其负载在凹土上,制得TiO2/凹土光催化剂,用其处理活性深蓝K-R模拟印染废水,通过改变溶液初始浓度,考察TiO2/凹土光催化剂对活性深蓝K-R模拟印染废水的脱色情况,并进行动力学研究.结果表明:溶液初始浓度越低相对去除率越高,但绝对去除量随初始浓度的增大而增大；光催化降解符合一级动力学方程.

| Abstract: | TiO2/Attapulgite photocatalyst loaded different TiO2 was prepared through attapulgite loading TiO2 Nanopowder synthesized by Sol-gel,using the samples of TiO2/attapulgite prepared as photocatalysts to decolorize reactive deep blue K-R.The effects of some factors,such as reactive deep blue K-R initial concentration,and light intensity on the photodegradation are discussed.The experimental results show that relatively decolorization ratio increases as initial concentration reduces,but absolute quantity increa... |
