UV/H2O2降解水中磺胺嘧啶影响因素及机理OA北大核心CSCDCSTPCD
Influencing factors and mechanism of sulfadiazine degradation by UV/H2O2
利用UV/H2O2光氧化反应器降解水中的磺胺嘧啶,考察了H2O2投量、pH值、紫外功率等因素对去除效果的影响,同时对反应动力学及降解产物进行了分析.结果表明,在紫外辐照与H2O2氧化共同作用下,UV/H2O2降解水中磺胺嘧啶效果显著,去除率达90％以上,其降解过程符合一级反应动力学模型(R2 =0.991 2).H2O2投量与磺胺嘧啶降解速率常数具有良好的线性关系,H2O2投量由0.03增大至1.50 mmol·L-1,反应速率常数由0.048 …查看全部>>
The UV/H2O2 photo-oxidation reactor was applied to degrade sulfadiazine solution.The effect of H2O2 concentration,initial pH value,UV light power and sulfadiazine concentration on removal efficiency were investigated.The reaction kinetics and degradation products were also analyzed to full understand the degradation process.The results showed that the UV/H2O2 process was effective for the degradation of sulfadiazine with a removal efficiency above 90％,and th…查看全部>>
