摘要
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.
The authors set up the procedures to determine the total mercury and different mercury species in rain samples using two-stage gold amalgamation cold vapor atomic adsorption spectrometry method. It has been showed that the detection limit of this method was below 0. 5ng Hg·l-1, if 100ml rain sample was used. The recovery ranges and the relative standard deviation were 96% to 105% and less than 5.3% respectively. This method can also be used to determine Hg species in other natural water.
