| 摘 要： | 采用高温干灰化法处理豆油、棉籽油和芝麻油样品（４８０℃、４０小时），将常规火焰原子吸收进样装置改成微量注射进样后测油中锌含量，每次进样量为３０μＬ，并对最佳进样条件进行了实验。特征浓度为０．０９８μｇ／ｇ；检测限为０．００３６８μｇ／ｇ；相对标准偏差为２．６％；回收率分别为９８．９％，１０７．８％，９２．９％；三种植物油中锌含量分别为９．６７，１．４２和１．７７μｇ／ｇ。

| Abstract: | A method for the determination of zinc in the soybean, cottonseed and sesame oils by FAAS with trace injection technique was discribed in this paper. The injection volume was 30 microL. The characteristic concentration and the detection limit were 0.098 and 0.00368 microg/g, respectively. The relative standard deviation was 2.6% and the recoveries were in the range of 92.9%-107.8%. The contents of zinc in the samples were 9.67, 1.42 and 1.77 microg/g, respectively. |
