摘要
生物样品经消化处理后,用火焰原子吸收光谱法测定样品中锌、铜和锰的含量,平均加标回收率为97.3%—102.4%,相对标准偏差(RSD)为0.65%—1.40%。锌、铜和锰在给定范围内呈现良好的线性关系,相关系数分别为0.9994、0.9994和0.9983,方法简便,快速,结果可靠。
The amounts of Zn,Cu and Mn in biological samples were measured by FAAS after digesting with HNO3-HCIO4 （4 ： 1,V/V）. The relative standard deviations were between 0. 65%- 1.40% with the recoveries of 97. 3%-102. 4%. The calibration curves were linear with good correlation coefficients （r〉0. 998）. The method was simple, rapid with satisfactory results.
