摘要
介绍了一种在稀硫酸介质中 ,应用NO-2 对溴酸钾氧化酸性铬蓝K褪色反应的催化作用 ,测定环境水样中痕量NO-2 的方法。方法检测限为 0 0 0 2 8mg/L ,相对标准差 (n =6 )小于 2 6 % ,加标回收率在 91%～ 10 5
Catalytic spectrophotometric determination of NO 2 - in environmental water samples using potassium bromate-acid chrome blue K serial was research in medium of thin sulfuric acid. Detection limit was 0 002 8 mg/L,relative standard deviation ( n =6)was less 2.6%, sampling recovery rate was between 91%～105%.
