ICP-AES Determination of Trace Elements in Different Parts of Crayfish with Microwave Assisted Sample Digestion

The crayfish sample was digested by microwave digestion,and the amounts of trace elements in 5 different parts of crayfish were determined by ICP-AES.The wavelengths of 317.93,327.396,285.213,213.856,396.152,259.940,334.941,213.618,259.372,589.592,233.527,766.491nm were selected as analytical lines for the determination of Ca,Cu,Mg,Zn,Al,Fe,Ti,P,Mn,Na,Ba and K.Values of detection limit of trace elements found were in the range of 1.6-32.3 μg·L-1.The proposed method was used in the analysis of crayfish sample,giving values of RSD′s (n=6) for the 12 elements in the range of 0.66%-2.96% and values of recovery in the range of 93.3%-111.1%.
