Document Type and Number:
Japanese Patent JPH0742261
Kind Code:
B2
Abstract:
Novel ortho alkoxy substituted phenyl oxime compounds which are useful for selectively separating and recovering palladium from aqueous compositions and mixtures containing palladium and other metals are disclosed. Also disclosed is a method of separating and purifying palladium which is present in s solution with at least one other platinum group metal by adjusting the pH of the solution to from about 0 to 5, contacting the acidified solution with an ortho alkoxy substituted phenyl oxime compound by means of solvent using solvent extractions techniques, separating the aqueous phase from the organic phase containing substantially all of the palladium in association with the oxime compound, and stripping the palladium from the association with the oxime compounds in the organic phase by extraction with an aqueous ammonia solution.
