摘　　要：目的 白砂糖是甘蔗糖业的主要产品,是人们日常生活中普遍食用的甜味剂.了解白砂糖中的微量元素营养成分,为健康吃糖提供科学依据.方法 采用硝酸和高氯酸消解法处理样品,用电感耦合等离子体质谱法（ICP-MS）测定白砂糖中的微量元素.结果 14种微量元素的检出限为0.336 1～11.63 μg·L-1,方法的准确度为95.0％～110.0％,方法精密度为1.30％～5.32％.结论 方法简便、快速、准确,可作为白砂糖中微量元素含量常规的测定方法.Objective Sugar cane sugar is the main product is the people＇s daily life commonly consumed sweetener. Understanding of trace elements in white sugar nutrients, provide a scientific basis for a healthy sugar. Methods Eliminate acid and perchloric acid digestion process samples by inductively coupled plasma mass spectrometry （ICP- MS） determination of trace elements in white sugar. Results 14 kinds of trace elements in a detection limit of O. 336 1 - 11.63 μg L-1 , accuracy of the method was 95.0% - 110.0%, precision of the method was 1.30% - 5.32%. Conclusion The method is simple, rapid, accurate, and can be used as sugar content of trace elements in the conventional method.
