黑果枸杞样品经微波消解处理,采用电感耦合等离子体-质谱法测定样品中钾、钠、钙、镁、铁、锌、铜、锰、钴、镍、铅、砷、汞、镉、铬等15种微量元素的含量。方法快速准确、灵敏度高,各元素的线性系数均大于0.9997,加标回收率在92.60%—103.20%之间,相对标准偏差小于5%。 Samples of black wolfberry were digested by microwave, and potassium, sodium, calcium, magnesium, iron, zinc, copper, manganese, cobalt, nickel, lead, arsenic, mercury, cadmium and chromium were determined by inductively coupled plasma-mass spectrometry 15 kinds of trace elements content. The method is rapid and accurate with high sensitivity. The linear coefficients of each element are all greater than 0.9997. The recoveries of spiked samples ranged from 92.60% -103.20% with relative standard deviations less than 5%.
