摘要
应用双硫腙分光光度法，测定贝壳粉中痕量的汞，结果表明：测定的灵敏度和标准回收率高，相对误差小，效果好，贝壳粉中汞的含量小于２．１ｍｇ／ｋｇ．
By means of dathizone spectro photometric analysis method, the trace Hg 2+ in the shell powder was determined. The results showed that the sensitivity and recovery rates were high, and the relative error small and the effects good. The Hg 2+ content in the shell powder was less than 2.1 mg/kg.
