Determination of 20 Elements in Silkworm Chrysalis,Scorpion and Sea Intestine By ICP-AES

Samples of silkworm chrysalis,scorpion and sea intestine were prepared by micro wave-assisted digestion and 20 elements in the prepared sample solution were then determined by ICP-AES.Conditions of digestion were experimentally selected.The results of the presented method were compared with those of the conventional acid degestion.The presented method was simple to operate and has a high sensitivity and low detection limits of 0.01-0.12 mg·L-1.RSD′s of the method were in the range of 1.4%-4.6%.
