Simultaneous Determination of Arsenic and Mercury in Purified Water by HG-ICP-AES

本文建立了氢化物发生 ICP- AES法同时测定纯净水中砷和汞的方法。检出限分别为 As 1.7μg/ L、Hg0 .1μg/ L,方法精密度 ( RSD)为 As3.4 6%、Hg2 .85% ,回收率为 As92 %— 110 %、Hg90 %— 113%

A HG\|ICP\|AES method for simultaneous determination of arsenic and mercury in purified water is proposed.The detection limit of arsenic and mercury is 1.7μg/L and 0.1μg/L respectively.The RSD for arsenic is 3.46% and for mercury is 2.85%.The recovery for arsenic is in the range of 92%—110% and for mercury is in the range of 90%—113%.
