Separation method of palladium from silver electrolyte
An electrolyte and desorption technology, which is used in the improvement of process efficiency, photography technology, instruments, etc., can solve the problems that the electrolyte cannot be directly returned to the silver electrolysis, thiourea enters the silver electrolyte, and the separation process is not thorough enough, and the purification time is reached. The effect of short, high recycling rate and strong practicability
