Qısa məlumat

The degradation of para-nitrophenol (PNP) pollutant under visible light (ZnCo2S4/CuO/PMS/Vis) via ZnCo2S4/CuO heterojunction activated peroxymonosulfate has been investigated in detail. The results indicate that 50 % ZnCo2S4/CuO performs best under light conditions, and after adding 4 mM PMS, the degradation rate of PNP reaches 98 %. The study systematically examines the effects of important parameters (PMS dosage, pH, and coexisting anions) on PNP degradation and verifies the excellent performance of the photocatalysis-activated PMS system through comparative experiments. Electron paramagnetic resonance (ESR) and free radical quenching experiments revealed that 1O2 contributes the most to the degradation performance of PNP.
