【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。更多还原

【Abstract】 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.更多还原
