IRIS/AP-ICP-AES法同时测定地表水中的Cu、Pb、Zn、Mn和Cd

Simultaneous Determination of Cu, Pb, Zn, Mn and Cd in Surface Water by IRIS/AP-ICP-AES

采用铜试剂富集和 IRIS/AP- ICP- AES法同时测定了地表水中的 Cu、Pb、 Zn、Mn和 Cd。优选出最佳仪器工作条件和被测元素分析谱线。讨论了水样中主量元素的干扰。实验结果表明本法精密度高 ,检出限低 ,回收效果好 ,结果准确 。

IRIS/AP\|ICP\|AES was used to simultaneously determine Cu, Pb, Zn, Mn and Cd in surface water after enriched by (C 2H 5) 2NCS 2Na·3H 2O. The analytical conditions were optimized and the best spectrum lines were selected. This method is precise and sensitive with low detection limit. It can be applied to the routine monitoring of the surface water. The interference of co\|existing elements was also discussed.
