▎ 摘　　要

NOVELTY - Processing of dye wastewater, involves degrading dye using lutetium-praseodymium-co-doped zinc oxide/graphene composite photocatalyst under visible light irradiation. The molar ratio of lutetium and zinc oxide is 0.01-0.03. The molar ratio of praseodymium and zinc oxide is 0.02-0.04. The mass ratio of graphene and zinc oxide is 1:3-4. The organic dye is methyl orange or rhodamine B. USE - Processing of dye wastewater. ADVANTAGE - The method enables effective degradation of organic dyes in wastewater by promoting the absorption intensity of visible light, using a photocatalyst, which can be prepared by a simple method.
