摘　　要：应用硝酸作基体改进剂 ,石墨炉原子吸收光谱法直接测定尿中痕量锰。方法简便、快速、准确 ,灵敏度高。方法的检出限为 0 .0 80 μg·L- 1,回收率为 97.2 %。对锰含量为 5 μg·L- 1的尿样测定 7次的相对标准偏差为 3.16%Diluted nitric acid is used as matrix modifier in the direct GF AAS determination of trace amounts of manganese in urine. Optimum condition for the determination is studied thoroughly. The detection limit of the method is found to be 0.080μg·L -1 . An average recovery of 97.2% is obtained by the standard addition tests. The RSD obtained from the data of 7 determinations at the concentration level of 5μg·L -1 is 3.16%.
