摘要
为了方便、快速、准确地检测大豆磷脂软胶囊中铅、铬、镉、砷4种微量重金属元素的含量,建立了一种冷冻快速粉碎-微波消解的前处理方式,采用电感耦合等离子体质谱仪(ICP-MS)进行测定。试验结果表明:经冷冻快速粉碎后的软胶囊壳颗粒均一;微波消解耗时短、操作简便、耗费试剂少,ICP-MS测定结果显示铅、铬、镉、砷4种重金属的平均回收率在82. 6%～92. 9%之间。试验结果满意,可为日常工作中测定软胶囊类产品中重金属前处理作参考。
In order to detect four kinds of trace heavy metals, Pb, Cr, Cd and As content, coupled plasma mass spectrometer （ICP - MS） in soft capsule of soybean phospholipids by inductively conveniently, quickly and accurately, a kind of pretreatment method of refrigeration smashing - microwave digestio established. The results showed that soft capsule shells treated by refrigeration smashing presented and uniform particle size. In addition, microwave n was small digestion had advantages of short time, simple operation and less reagent consumption. Four metals （Pb, ICP - MS, and their recovery rate was between 82.6% Cr, Cd and As） were quantitative analyzed by and 92.9%. The test could provide reference for the quantification of heavy metals in soft capsule.
