| 摘 要： | 采用电感耦合等离子体原子发射光谱（ICP—OES）法对葡萄酒中14种元素含量进行测定，对样品前处理方法和检测条件进行了研究，建立了一套完整的分析方法．样品前处理采用80qC水浴加热除去酒精，加入硝酸和双氧水对样品进行消解，此方法简单易行，元素损失少．用ICP—OES法测定葡萄酒中14种元素含量，标准曲线的线性关系良好，检出限低，回收率为92．0％一109．4％，精密度为0．54％一4．25％，测定结果令人满意．

| 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 H2O2 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%. |
