Indirect Spectrophotometric Determination of Hydroxylamine Hydrochloride with Copper(II)-phosphate-molybdate Heteropoly Acid

Zhan Cheng Guo

Abstract

An indirect spectrophotometric method for the determination of hydroxylamine hydrochloride was developed.It was based on the heteropoly blue,produced from the redox reaction of hydroxylamine hyˉdrochloride with copper(Ⅱ)-phosphate-molybdate heteropoly acid.Beer′s lawwas obeyed in the range of0to7.68μg/mLwith a correlation coefficient of0.9996.The RSD was0.43%(n=6).The method has been used to determine the industrial grade of hydroxylamine hydrochloride with satisfactory result.
