本文报道了一种简便测定饮用水中痕量溴酸盐的光度分析方法。原理：在盐酸介质中，溴酸盐被偏重亚硫酸盐（ｍｅｔａｂｉｓｕｌｆｉｔｅ）还原成溴，溴与还原型品红反应，生成红色的溴异戊酰脲化合物，于波长５３０ｎｍ处比色定量，检出限高达１μｇ／Ｌ，测定５μｇ／Ｌ溴... This paper reports a simple method for the determination of trace bromate in drinking water by spectrophotometry. Principle: In hydrochloric acid medium, bromate is reduced to metabisulfite (metabisulfite), and bromine is reacted with reduced magenta to produce red bromo-isovaleryl compound, which is quantified by colorimetry at wavelength of 530 nm and detected Limit up to 1μg / L, determination of 5μg / L bromine ...
