Study on the reason of lossing silver during burning off mercury

本文重点研究提出了银在灼烧除汞时损失的原因及对策，并据此拟定了氯化钠熔矿后，不经任何分离，直接用双硫腙萃取光度法测定银的改进方法。

The paper mainly study on the reason of lossi ng Ag during burning off Hg and propose the way to deal with the situation.Accordingly we draw up the improving method of direct measure Ag using dithizone extraction spectrophatometry after NaCl scorification and without any seperation.
