摘　　要：本研究利用微波消解和石墨炉原子吸收技术建立了一种用于准确测定百合中镉含量的方法,并将其应用于实际样品检测。实验结果显示,在最佳仪器条件下,镉元素在0~2.0μg·L~(-1)线性关系良好,相关系数为0.999 3,方法检出限为0.000 4 mg·kg^(-1)。在3个加标水平下,样品的平均回收率在99.97%~101.67%,相对标准偏差(Relative Standard Deviation,RSD)在1.07%~7.07%。实际样品检测结果显示,该方法简便、高效、准确且精密度高,适用于百合中镉含量的测定。This study established a method for accurately determining cadmium content in lilies using microwave digestion and graphite furnace atomic absorption technology,and applied it to actual sample detection.The experimental results showed that under the optimal instrument conditions,the linear relationship of cadmium element was good in the range of 0~2.0μg·L-1,with a correlation coefficient of 0.9993 and a detection limit of 0.0004 mg·kg-1.At three spiked levels,the average recovery rate of the samples ranged from 99.97%to 101.67%,with a relative standard deviation(RSD)of 1.07%to 7.07%.The actual sample testing results show that this method is simple,efficient,accurate,and precise,and is suitable for the determination of cadmium content in lilies.
