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AgCl-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.
