一、前言早在Snell&Snell:Colorimetric Method ofAnalysis一书中就谈到用钼蓝比色测定微量砷的方法,不过并未被广泛应用。在目前各厂矿实验室中,关於微量砷的测定,大都采用卑磷酸钙法。现在谈谈用钼蓝比色测定微量砷的几点体会,供大家在测定时作参考: 方法概要:用蒸馏法将三氯化砷(AsCl_3)吸收於水 First, the preface As early as Snell & Snell: Colorimetric Method ofAnalysis on a book about the determination of trace arsenic molybdenum blue color method, but it has not been widely used. In the current factories and mines laboratories, the determination of trace amounts of arsenic, most commonly used calcium phosphate method. Now to talk about the determination of trace arsenic with molybdenum blue color of a few experiences, for everyone in the determination for reference: Summary: The distillation of arsenic trichloride (AsCl_3) is absorbed in water
