Abstract

PURPOSE: To separate and recover Pd in high yield as sodium chloroplalladate by a method wherein non-electrolytic palladium plating waste liquid is added with HCl and iron powder, and precipitated cpd. is separated and dissolved in HCl, then the solution is evaporated and dried.
CONSTITUTION: Non-electrolytic Pd plating waste liquid contg. Pd is made acidic by adding HCl, then iron powder is added and heated to produce hydrogen. By the reducing action of produced hydrogen, red crystal of sodium chloropalladate is precipitated. The red precipitate is separated from the liquid and dissolved in HCl and the solution is evaporated and dried, so that sodium chloropalladate crystal is separated and recovered in high yield.
