多硫化物浸金溶液中总多硫根离子浓度的测定

Determination of the total concentration of polysulfide ions in the polysulfide solution of gold leaching

多硫化物溶液是一种非氰化浸金体系，其中的有效成份是多硫根离子。结合实际需要，提出了测定总多硫根离子浓度的方法，即ＥＤＴＡ容量法。该方法简单易行、操作方便，测定结果重复性好。

The polysulfide solution is one of non cyanidation systems of gold leaching in which polysulfide ions are the main effective components.A new determination method for analysis of the total concentration of polysulfide ions in the polysulfide solution was proposed in this paper.
