Abstract:
The assay and determination method for the 12 trace elements of the white spirit is fixed by making use of the ICP-AES, of which, the optimum analysis conditions are comprehensively determined by way of the research of the factors such as the digestion way of the white spirit, the analysis parameters of the apparatus, the deduction of the interference among the elements, the background correction and the selection of the element spectral lines etc.. The proposed method shows that the recovery for the 12 elements is in the range between 93% to 109%.
