| Abstract: | 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. |
