[Study of determination method of trace elements in white jade snail].
The contents of six trace elements, Ca, Mg, Fe, Zn, Cu and Co, in white jade snail were determined by ICP-AES and AAS using nitrifying method of high pressure nitrifying pot. The results of two analysis methods were compared, showing no obvious differences. The recoveries were 92.4%-103.0%, and the relative standard deviations were less than 2.98%. The experiment proved that white jade snail contains rich useful trace elements, and is a kind of green food with high nutrition.
