Determination of content of 14 trace elements in grape wine by ICP- OES
Abstract：ICP- OES was adopted in the determination of 14 elements in grape wine. Pre- treatments of grape wine samples and detection conditions were studied. A complete analysis method was established. In the pre - treatment period, alcohol in grape wine was evaporated in water bath at 80℃. Then HNO3 and H202 were added to digest the samples. The pre - treatment method is simple and feasible and the loss of elements is less. The content of 14 elements in grape wine was detected by ICP - OES, and the results were all satisfactory with a good linearity of standard lines, low detection limits, a recovery between 92.0% - 109.4% and a precision between 0.54% -4.25%.
