摘要
本文提出一种采用固体进样,以银的标准溶液制作校正曲线,石墨炉原子吸收光谱法直接测定地质样品中Ag的快速方法,选择最佳分析条件时,该方法的RSD为1.7％～5.7％。测定样品中银的结果与参考值相符。
This paper presents a method for rapid determination of silver in geological samples by solid sample introduction in GFAAS. The calibrated curve can be drawn, using the results of standard solution of silver. The optimum conditions of analysis are selected. Related standard deviations ( RSD ) of the method are appro-ximately 1.7%~5.7%. The analytical results conform to those that are certified.
