井水过滤前后微量元素的测定

Determination of Trace Elements in Well Water front and behind Filter

为探讨广州龙洞井水过滤前后微量元素的含量,采用火焰原子吸收法测定了龙洞井水过滤前和过滤后水中Li、Ca、Mn、Zn、K、Mg、Na、Fe、Cu、Pb 10种微量元素的含量。结果表明,龙洞井水过滤前后微量元素存在一定的差异。同时对井水中各元素进行了回收实验,回收率在97%~103%之间。该法简便、快速、准确、灵敏度高、再现性好。

To discuss the content of trace elements of in well water front and behind f ilter,f lame atomic absorbtion spectrometry were used in measuring 10 microelements(Li,Ca,Mn,Zn,K,Mg,Na,Fe,Cu,Pb) contained in well water from Longdong of Guangzhou.The results show that the concentrations of trace elements of front and behind filter well water have differents.The results show that,the rate of reclaimation is about 97%～103%.This method was proved to be not only simple and rapid,but also of high sensitivity and good...
