摘要
本文提出了钴(Ⅱ)催化H_2O_2氧化茜素红S褪色反应体系的新催化光度法。本方法灵敏度高,选择性好,精密度高(测2μgCo(Ⅱ)6次,RSD=1.43%),适用于水样中痕量钴(Ⅱ)的测定。
n this paper a new method for thecatalytic photometric determination of tracecobalt has been introduced based on cobaltcatalysing oxidation of alizarin red S byhydrogen peroxide,The method has goodselectivity and precision(n=6 ,RSD=1.43%at a level of 2μg Co(Ⅱ)).It hasbeen used to determine trace cobalt in waterswith satisfactory results。
