1 引言 许多样品通常要求测定溴和碘的含量,往往含量甚微,电导检测的离子色谱法达不到要求。本文研究了离子色谱安培法连续测定溴和碘的可行性,拟定了一个快速、简便,无干扰的、可同时测定各种样品中痕量溴和碘的方法。本法以艾斯卡半熔,抗坏血酸为还原剂,使样品中的碘全部转变成适合于离子色谱安培法检测
1 Introduction Many samples usually require the determination of bromine and iodine content, often content is very small, conductivity detection of ion chromatography can not meet the requirements. In this paper, the feasibility of continuous determination of bromine and iodine by ion chromatography with amperometric method was studied. A rapid, simple and non-interference method for simultaneous determination of trace bromine and iodine in various samples was developed. This Act to Esca half-melting, ascorbic acid as a reducing agent, so that all samples of iodine into suitable for ion chromatography amperometric detection
