本文建立了两次金汞齐冷原子吸收光谱法测定雨水样品中总汞及活性汞、次活性汞和惰性汞的方法.该方法的最低但出限为 0.5ng·1~(-1).回收率为96—105%,精密度RSD≤5.3%.该方法还可用于其它天然水体中汞的形态测定.
In this paper, two mercury amalgam atomic absorption spectrometry was established for the determination of total mercury, active mercury, secondary active mercury and inert mercury in rainwater samples. The minimum and maximum limits of the method were 0.5 ng · 1 -1. The recovery rate is 96-105% and the precision RSD is less than or equal to 5.3% .This method can also be used for the determination of mercury in other natural waters.
