【摘要】 具有蒽醌结构的染料是不易被降解的,活性艳兰KN-R是蒽醌型染料的典型代表.本试验采用自制的纳米二氧化钛为光催化剂,以含有活性艳兰KN-R的模拟废水为降解对象,在一定的光源条件下成功的降解掉染料废水中的污染物.对影响活性艳兰KN-R废水溶液的光催化降解的各种条件(pH值、光源、溶液的初始浓度、催化剂的用量)进行了摸索,描述了催化剂降解低浓度活性艳兰KN-R的动力学规律,并对催化剂的回收再利用进行了可行性研究.
【Abstract】 It is difficult to degrade the anthraquinone dye, and reactive blue 19 is the classic representative, with the loop of anthraquinone. With self-prepared titanium as the photocatalyst, and water containing reactive blue 19 as the degradation object, the pollute was assuredly degraded under illumination. We researched the factors, including the value of pH, illumination, original concentration and the dose of catalyst, characterized the kinetics discipline of low concentration solution, and discussed the possibility of recycling use the self-prepared titanium.
