摘要
研究结果表明 ,原子吸收法测定银时Ag+ 和AgCl- 2 两种形态的原子化效果一致。本文建立了使用过量HCl,以Ag Cl- 2 形态测定铅矿石中Ag的方法 ,避免了因实验室Cl- 的沾污导致结果偏低。比较了几种溶样方法 ,研究了铅基对测Ag的影响情况。
It was found that the atomization effect are the same both for Ag + and AgCl - 2 during the determination of silver by AAS. A method for determination of silver in lead ore by AAS was estalished, in which silver was in the state of AgCl - 2 with excess HCl avoiding the results to low caused by Cl - pollution in laboratory. Some methods for dissolving sample were compared and the influence of lead matrix on determinig silver was studied.
