摘要
用固载的二氧化钛光催化降解偶氮染料酸性大红G溶液。研究了染料初始浓度、搅拌和溶解氧 (DO)、H2 O2 浓度、pH值和乙醇对降解的影响。结果表明选择适当的实验条件可以缩短染料的脱色时间。
The photo-catalytic degradation of an azo-dye acid red G. in water has been investigated over immobilized titanium dioxide. The effect of operational parameters, i.e. initial dye concentration , agitation and DO,H 2O 2 concentration, pH of the solution and ethanol concentration on the photo-catalytic process has been examined. It can be stated that the removal of color, after selection of optimal operational parameters,can be achieved inrelatively short time.
