摘要
本文提出用简易氢化物发生系统与ＩＣＰ联用，测定自来水和矿泉水中痕量砷的方法．用氢氧化铁共沉淀水中痕量砷，并用离心机富集和分离沉淀，快速、简单，选择最优化反应条件和工作条件，方法的检测限为０．００２ｕｇ／ｍｌ，精密度为２％，回收率在９０－１０４％之间．
Presented in this paper is a method of determining trace artsenic in water by hydride generdtionsystem with ICP emission spectro-metry.By applying hydride iron mix-deposited trace arsenicin water and the centrifugal machine rich collection,and separate deposition,the method is verypuick and simple.By selecting optical reaction and operation conditions,detection limit of themethod is 0. 002μg/ml,and precision is as high as 2%.Recovery rate is between 90-104%.
