Abstract: [目的]建立简便、可靠的石墨炉原子吸收测定血镍的方法.[方法]以新会区某镍氢电池厂82名作业工人为对象,采用标准加入法,以Triton X-100+氯化钯混合液作基体改进剂稀释样品直接测定.[结果]作业工人血镍浓度在1.39~48.16μg/L之间.标准曲线在0~50μg/L范围内线性良好,该方法检出限0.62μg/L,回收率在96.1%~104.2%之间,吸光度Y对浓度C的回归方程:Y=0.00483 C+0.00481;相关系数0.9993(P<0.05).[结论]使用混合基体改进剂,以石墨炉原子吸收法测定血镍,操作简便,结果准确可靠,适用于日常工作中血镍的批量检测.
