摘要
采用了离子交换分离富集矿样中的锰，该系统与原子吸收测量技术相结合，实现了富集-原子吸收法联用测定矿样中的锰,该方法检出限（3σ）为0．018μg／L，线性范围0．01—0．5μg/L，相对标准偏差RSD为3．59％。该法应用于标准样品的测定其结果与标准样值相符。应用于实际矿样的测定，加标回收率在96．7％-104．3％之间，结果满意。
A rapid and sensitive method for concentration and separation of trace manganese based on ion exchange process has been developed. The detection limit of the method is 0. 018μg/L. The recoveries are in the range of 96.7% to 104.3% and The relative standard deviations（RSD） are 3.59%. The method has been successfully applied for the determination of manganese in certified reference material GBW07268 and other sample.
