Waste-conductive silver pastes are considered an important secondary resource. The recovery of metals from waste-conductive have high economic value. traditional cyanidation method has serious environmental pollution, while the thiosulfate is green, environmentally friendly, and become a viable alternative for metal extraction. exposure complexes to ultraviolet (UV) light been found generate sulfides, this can be used realize valuable metals. In study, extraction copper conductive was systematically performed using sodium thiosulfate, effects concentration, solid-to-liquid ratio, photolytic process temperatures were investigated. products characterized X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, transmission photoelectron spectroscopy. After 4 h UV irradiation with wavelength 254 nm, 87% 49% recovered transformed into sulfide, respectively. This study demonstrates that applied in combination photolysis technology recover friendly manner.
