摘　　要：以氢化物生成法为砷原子化手段,采用原子吸收分光光度法测定番茄红素中砷含量。本实验选定条件下,砷的检测限为8×10-10,精密度RSD为3.2%,准确度以回收率计为94.5%。结果表明该方法专属性好,灵敏度高,线性范围宽,测定结果准确可靠,适用于番茄红素中砷含量的测定。To establish a HG-AAS method for the determination of micro-amount of arsenic in lycopene. Arsenic was deter-mined by the conditions selecting to allow lower limit of determination of 8 ×10^-10,relative standard deviation of 3.2%,. and the recovery of 94.5%.This method is reliable in terms of precision, accuracy, specificity, detectability, linearity. It is applicable to the detection of arsenic in lycopene.
