钯络合液中分离银的工艺探索与研究

The exploration and research of separation of silver from palladium complex solution

本研究针对钯和银的氯配合物、氨络合物在转化为沉淀时的最优pH不同,通过控制酸度条件,使银首先高效沉淀、钯仍存于溶液中,从而实现银钯的高效分离。

In this paper,the optimal pH of chlorine and ammonia complexes of palladium and silver is different when they are converted to precipitation. By controlling acidity conditions, silver is precipitated efficiently first and palladium is still in solution, so as to realize the efficient separation of silver and palladium.
