摘要
本文采用沈阳分析仪器厂产４０２型原子吸收分光光度计，在标准溶液中加入ＮａＣｌ溶液作为基体改进剂，用火焰原子吸收光谱法直接测定红细胞中Ｃｕ、Ｚｎ、Ｆｅ的含量，不仅消除基体干扰，而且提高了测定Ｃｕ和Ｚｎ的灵敏度。Ｃｕ、Ｚｎ、Ｆｅ的平均回收率为１０１％、１０３％及９９％；相对标准偏差分别为４．６％、２．２％及９．６％。
The determination of Cu,Zn,Fe in erythrocytes by flame atomic absorption spectropho tometry(FAAS) is described in the present paper.NaCl solution is added inter the standard so lution.The interference of the matrices is overcomed and sensibility of the determination of Cu,Zn is increased.The recovery of Cu,Zn,Fe in erythrocytes is 101%,103% and 99% respective ly,the relative standard deviation is 4.6%,2.2% and 9.6% respectively.
