摘　　要：本文采用火焰原子吸收光谱法测定血清中锌含量．样品经用0．16mol/L硝酸5倍稀释后，直接上机测定．采用黏度与稀释了的血清样相近的锌标准溶液(含10%甘油基质)．本法血清锌检出限为0．03mg/L，取低、中、高三种浓度血清分别进行六次测定，变异系数为1．5%～3．2%，用标准加入法进行回收实验，得回收率为99．0～100．2%．人体血清中存在一定浓度的无机组分不干扰测定．This paper introduces the method to determine Zinc in serum by flame atomic absorption Spectroscopy.The sample diluted by 0.16mol/L ni tric acid is determined with the Zinc standard Solution whose viscosity is same t o the sample (including 10% glycrine substratum).The minimum detective limit is 0.03mg/L.Through determining three kinds of the sample different in density,the variable coefficient is 1.5%～3.2%.The recovery of the standard method is 99.0% ～1 00 2%.There is no disturb by a certain density inorganic substances in serum of human body.
