摘要
探讨进口葡萄酒中微量元素的浓度及其分布情况。采用电感耦合等离子体原子发射光谱法(ICP-AES)对葡萄酒中钙、钾、钠、镁、磷等5种微量元素进行了分析测定。采用微波消解样品,在优化的实验条件下,5种微量元素标准曲线的相关系数均大于0.9991,加标回收率在90.6%~99.7%。相对标准偏差为1.2%~4.0%。该方法简便,快速,准确性好,为进口葡萄酒中微量元素分析提供了一种有效的方法。
To investigate the concentration and distribution of trace elements in imported grape wine.Five trace elements,such as calcium,potassium,sodium,magnesium and phosphorus in grape wine,were analyzed and determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).Under the optimized experimental conditions,the correlation coefficients of the standard curves of the five trace elements were all greater than 0.9991.The recoveries were 90.6%~99.7%.The relative standard deviation is 1.2%~4.0%.The method is simple,rapid and accurate,and provides an effective method for the analysis of trace elements in imported grape wine.
