本文采用扩大样品处理量，用稀硝酸润湿──炭化——高温灰化方法进行样品预处理，空氧一乙炔火焰直接测定溶液，氘灯扣除背景吸收原子吸收法，测定植物性食物中锌、铜、铁、锰、镉、铅元素的含量。平均回收率：锌 １０８％、铜 ９９％、铁 １１８％、锰９８％、镉９７％、铅 ９８％相对标准偏差：锌２．０２％、铜１１．２４％、铁１２．４１％、锰１．２７％、镉６．９０％、铅７．０３％ In this paper, samples were treated to increase the amount of treatment, with wet dilute nitric acid ─ ─ carbonization - high temperature ashing sample pretreatment, air oxygen-acetylene flame direct determination of solution, deuterium lamp background subtraction absorption atomic absorption method, determination of zinc in plant foods , Copper, iron, manganese, cadmium, lead content. The average recovery was 108% for zinc, 99% for copper, 118% for iron, 98% for manganese, 97% for cadmium and 98% for lead. The relative standard deviations for zinc were 2.02% for zinc, 11.24% for copper, 12.41% for iron, 1.27%, cadmium 6.90%, lead 7.03%
