离子色谱法检测海水中常见阴离子的前处理法研究——电解银电极法

The Study of Pretreatment for the Determination of the Conventional Anion in Sea Water by IC——the Method of Electrolysing Argentine Electrode

提出一种采用电解银电极降低海水中大量Cl 的浓度的前处理法 ,以便海水中微量的Br ,NO3 以及SO4 2 可以采用快速、灵敏的离子色谱法检测 .该前处理方法简单 ,快速 ,所测量的离子回收率均在

The method of pretreatment to determine trace amounts of Br ,NO 3 and SO 4 2 in sea water by ion chromatography was proposed, by which the electrolysing argentine electrode was used to minimize the disturbance of Cl -. The results indicate that the method is simple, convenient, quick and efficient with recovery rates over 95 percent.
