摘　　要：本文采用石墨炉原子吸收法，以ＮＨ４ＮＯ３和Ｍｇ（ＮＯ３）２混合剂作基体改进剂，测定了人精子中微量元素铜和锌。其方法的特征质量分别为１０．００ｐｇＣｕ／０．００４４Ａ．Ｓ．，９．８０ＰｇＺｎ／０．００４４Ａ．Ｓ；平均回收率铜为９７．４２％，锌为１０１．９１％；铜和锌的精密度分别是４．１％和４．０３％。A method for the determination of Cu and Zn in man's sperm with NH4NO3 and Mg(NO3)2 as matrix modifier in graphite furnace AAS is described. The method is simple and rapid.The characteristic mass mo is 10. 00pg Cu/0. 0044 A.S and 9. 80pg Zn/0.0044 A.S.The recovery is 97. 46% (Cu) and 101. 91 % (Zn) respectively. The variation coefficient is 4' 1% (Cu) and 4. 03% (Zn) respectively.
