纳米二氧化钛光催化处理废水中亚硝酸根的研究

Study on the treatment of content of NO^(2-) in waste water through photocatalysis mechanism of nanometer titanium dioxide

综述了纳米二氧化钛光催化的机理 ,提出了测定废水中亚硝酸根的方法 ,探讨了纳米二氧化钛的用量 ,反应物起始浓度 ,空穴清空剂甲酸等因素对反应的影响 ,拟合出了反应动力学方程 ,并对空穴清空剂甲酸的作用机理提出看法。

In this paper photocatalysis mechanism of nanometer titanium dioxide were expounded,the measure of determining the content of NO^(2-) in waster water was presented.Influences of the dosage of nanometer titanium dioxide,the initial and the last concentration of reactants.methanoic acid on reaction were discussed.The chemical kinetics equation was drawn up and some ideas about reaction mechanism of methanoic acid was presented.
