燃烧法制备纳米 ZnO及光催化降解 甲基橙的研究

Zinc has catalysis ability in the system of H_2O_2 oxidize methyl orange in H_2SO_4 medium and the discoloration extent of methyl orange has a linearity to the content of zinc . Based on this fact a new photometric method for the determination of zinc was proposed .

在硫酸介质中， 锌对过氧化氢氧化 甲基橙的反应体系具有催化作用，且甲基橙被氧化后的褪色程度4SΔA与锌的含量有线性关系，据此建立了甲基橙褪色光度法测定微量锌的新方法。
