合金中金的分离和测定是用2M KCNO直接沉淀金并以氰酸金的形式称重。此时金能完全回收。剩余的金属用萃取法分离。本方法可用于14K“金焊料”的分析。
The separation and determination of gold in the alloy is direct precipitation of gold with 2M KCNO and weighing in the form of cyanic acid gold. At this point the gold can be completely recycled. The remaining metals are separated by extraction. This method can be used for 14K “gold solder” analysis.
