| 摘 要： | 本文探讨了土壤中汞的ICP发射光谱测定法。实验中使用的介质有HCl,HNO_3,H_2SO_4和HClO_4,还原剂是SnCl_O或NaBH_4。通过实验值与推荐值的对照,验证了方法的可靠性。本法灵敏度高,干扰少,动态范围宽。在1%HNO_3溶液中所达到的检测限分别为0.7和0.09ppb。

| Abstract: | It is reported in this paper that, by Comparison of using SnCl_2 or NaBH_4 as reducing age-nt and HCl, HNO_3, H_2SO_4 and HClO_4 as medium respectively, the determination of the mercuryin Soil by ICP-AES is available. By Contrast the experimental Values with the recommened Va-lue, Soows the reliability of this method. It is higher Sensitivity, fewer interrupter and of widerange of determination. In 1% HNO_3 Solution, the detection limits are 0.7 and 0.09 PPb respec-tively. |
