Photocatalytic Degradation of Industrial Dye Wastewater Using Zinc Oxide-Polyvinylpyrrolidone Nanoparticles

Abstract

Due to the lack of studies regarding the potential of polyvinylpyrrolidone (PVP) as capping agent in precipitation of zinc oxide (ZnO) nanoparticles, this research focused on the performance of ZnO nanoparticles with presence of PVP loading on photocatalytic degradation treatment for industrial dye wastewater. Three different samples of ZnO-PVP were successfully synthesized via precipitation method. The degradation rate of dye approached 90.61% under pH7 in the presence of ZnO-PVP (0.025g/L of PVP). The chemical bonds in ZnO-PVP was analysed using Fourier Transform Infrared Spectroscopy (FTIR).

Recent and Emerging Trends in Remediation of Methylene Blue Dye from Wastewater by Using Zinc Oxide Nanoparticles

“…In the presence of ZnO-polyvinylpyrrolidone (PVP) nanoparticles (0.025 g/L of PVP), Sidik et al (2018) proposed photocatalytic degradation of industrial dye effluent. During the precipitation type of ZnO synthesis, PVP was used as a capping agent.…”

“…The photocatalytic degradation of industrial dye effluent by ZnO-PVP NPs offers significant potential as an alternative treatment, according to researchers. It is an environmentally friendly treatment because no toxic by-products are produced [109,110].…”
