| 摘 要： | 测定硫化物中的晶格金是近年来的热门话题，研究者希望获得直接的测定数据以证明晶格金存在。尽管已经进行了许多研究工作，其中化学法用Ｈ２Ｏ２－ＨＣｌ、浓ＨＮＯ３体系分离矿物中的晶格金。本文实验证明室温下金微溶于浓硝酸，也溶于Ｈ２Ｏ２－ＨＣｌ，故前述化学法测定结果难以做为晶格金存在的依据。

| Abstract: | Several Kinds of methods of lattice gold determination have been given by now,but research workers pay much attention to the immediate determination. They separated ionic gold from sulfides by chemical method of H 2O 2 HCl,conc. HNO 3.But there are still a few questions our tests about the solubility of gold in nitric acid have testified that trace gold(Au 0) many dissolve in H 2O HCl,conc. HNO 3. |
