摘要
提出了以抗坏血酸作基体改进剂石墨炉原子吸收光谱测定水中铷的新方法.本法特征量为4.6pg Rb,检出限(3s)为 0.27μg·L^(-1)样品加标回收率为95%~110%.方法简便、快速、结果准确可靠.
A new method for determination of Rb in water by GFAAS with ascorbic acid as matrix modifier is proposed in this paper. The Characteristic mass of the method is 4. 6pg,and the detection limit is 0. 27 μg ?L-1(3s). The recoveries are 95% -110%. The method proposed has advantages of convenience、rapidity and reliability.
