▎ 摘　　要

NOVELTY - Method for photocatalytic selective metal leaching containing nitrile-amine solution system, comprises dispersing the metal-containing material to be dissolved into a mixed solution containing nitrile and amine components, adding photocatalyst, and introducing oxygen or adding substances that can generate oxygen, and irradiating light to dissolve the metal. The metal includes gold, silver, platinum, palladium, iron, copper, nickel, zinc and/or aluminum. USE - Method for photocatalytic selective metal leaching containing nitrile-amine solution system. ADVANTAGE - The method is mild, energy-saving, green, environment-friendly, low cost, convenient operation, and only needs to introduce photo-catalysis technology, without consuming too much energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a photo-catalytic selective metal dissolving agent.
