摘要
介绍了用王水回流消解法测定土壤中铜锌的方法。本法测定铜和锌的回收率分别为95%～103%和97%～102%,测得的铜和锌的相对标准偏差(RSD)分别为1.9%和0.5%,具有操作简单、快速、灵敏度高等优点。
The method of digestion with aqua regia reflux to determine the copper and zinc in soil was introduced.Recovery rate of copper and zinc were 95%～103% and 97%～102%,and relative standard deviation（RSD） of the measured copper and zinc were 1.9% and 0.5%.The method was simple,rapid and high sensitivity.
