▎ 摘　　要

NOVELTY - Enriching and separating gold, platinum and palladium comprises using graphene oxide as a photocatalyst to separate and extract gold, platinum and palladium step by step from a low-concentration gold-platinum-palladium mixture by controlling the pH of the solution and directly using sunlight. USE - The method is useful for enriching and separating gold, platinum and palladium. ADVANTAGE - The method: is feasible in practical operation; has high precious metal separation and recovery rate; and has potential industrial application value. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram for enriching and separating gold, platinum and palladium.
