PAR分光光度法测定微量钒

Spectrophotometric Determination of Vanadium Using 4-(2-pyridylazo)-resorcinol(PAR)

钒污染越来越受到广泛的关注,因此对于钒的测定方法的研究众多。在这些方法中,分光广度法受到广泛好评。4-(2-吡啶偶氮)-间苯二酚(PAR)可用于许多元素的光度试剂。研究了PAR和H2O2用于分光光度法测定钒的最适条件,以及反应的准确性和灵敏度。

Owe to much attention has been paid on the contamination of Vanadium, more and more meth- ods. among which spectrophotometry was widely praised, was applied to the determination of V. 4-（2-pyr- idylazo）-resorcinol （PAR） was used for the determination of many chemical elements. The optimum condi- tion of spectriphotopetric method using PAR and H2O2 was studied, and the same as the precision and sen- siticity.
