应用活性炭和离子交换树脂从提取金的工厂的排放液和循环液中提取金的先进工艺中,需要测定含量范围为0.002—0.1μg/ml的低浓度金。为此目的,所使用的分析方法,都是基于用异戊醇或其它有机
In advanced processes that use activated carbon and ion exchange resins to extract gold from the effluent and recycle fluids of gold extraction plants, low levels of gold in the range of 0.002-0.1 μg / ml need to be determined. For this purpose, the analytical methods used are based on isoamyl alcohol or other organic solvents
