摘要
本文研究了贵金属标准溶液除氯离子的有关问题,解决了高纯硝酸银中贵金属等杂质元素的标样配制,以硝酸银直接压样于普通电极中直流电弧激发,可测定99.0~99.99%的高纯银,该方法简便、快速、准确。
A fast speed precise method is proposed for the direct determination of 14 trace in 99. 0-99. 993% silver by direct-current arc AES, with chloride ion deprived of the precious metals standard solution most of the matrix interference can be eliminate. The recovery for the method is 91. 5-110% and the realive standard deviatio.n is 6. 0-14. 2%.
