Abstract:
A method was established to determination of 21 trace elements in fruit wine. After microwave digestion, the samples were determined directly by inductively coupled plasma mass spectrometry. Under the optimal conditions，the calibration curves for 21 metal elements were linear in the range of 0~10 μg/mL with correlation coefficients more than 0.999. The quantization limit of the method were ranged from 0.010 ng/g to 3.911 ng/g with RSD of 0.59%~4.16% (n=6)．The mean recoveries of 21 metal elements from spiked samples at the spiking levels of 0.001~3000 μg/g were ranged from 89.7% to 112%. The proposed method is fast, simple, sensitive and accurate, which can meet the demand for determining 19 metal elements in fruit wine.
