| 摘 要： | 采用王水消解样品,利用原子吸收分光光度法,对重金属元素(Cu、Pb、Zn、Cd)在成都市东郊土壤中的垂直分布进行了研究。该法对Cu的回收率为98%~104%,精密度为2.75%;Pb的回收率为95~97%,精密度为3.11%;Zn的回收率为99%~101%,精密度为2.31%;Cd的回收率为97%~102%,精密度为3.32%,测定方法简单、准确。

| Abstract: | A study on the the vertical distribution of heavy metal four kinds of elements in the east suburban soil in Chengdu was conducted by AAS after samples were digested by aqua regia. The recoveries and precisions were 98% - 104% and 2.75% for Cu, 95% -97% and 3.11% for Pb, 99% - 101% and 2.31% for Zn, 97% - 102% and 3.32% for Cd, respectively. The method proved to be simpl and accurate. |
