通过特殊液相沉淀法制备出纳米二氧化钛粉体，利用二氧化钛的催化性能及活性炭的分散性能，通过浸渍法得到活性炭负载的纳米二氧化钛，探究此催化剂在自然光照射下对工艺模拟废水——酸性品红溶液的降解率。探讨不同的复合比例、催化剂的投入量对光催化效率的影响以及催化剂回收再利用问题。结果表明，二氧化钛与活性炭质量比为2：1时的催化效果最好，对于160 mL质量浓度为10 mg/L的酸性品红溶液投入该催化剂1 g时催化效果最好，在50 min后，降解率达到98%，回收再利用的催化剂在50 min内降解率达到97%，与第一次的降解率相近。

By using special liquid precipitation method,nano titanium dioxide powder is prepared.Using the dispersing performance of the catalytic performance of TiO2 and activated carbon,the immersion method is used to obtain the nano-titanium dioxide dope with activated carbon. The catalyst for the inquiry process waste-water in natural light—the degradation rate of acid fuchsin solution is explored. Different composite propor-tions,adding amount of catalyst,catalyst recovery and recycling problems are discussed. The results show that the catalytic effects is the best when the proportion of titanium dioxide and activated carbon is 2:1.For 160 mL acid fuchsin solution with concentration of 10 mg/L,the catalytic effect is the best when adding 1 g catalyst. 50 min later,the degradation rate is 98%. The degradation rate of recovery and recycling catalyst reaches 97%in 50 mins,which is similar with the first degradation rate.
