A study on the photocatalytic degradation of p-Nitroaniline on glass plates by Thermo-Immobilized ZnO nanoparticle

Abstract

ZnO nanoparticles have been synthesized via a hydrothermal technique has been utilized for synthesizing ZnO nanoparticles, which had been immobilized on glass plates for the purpose of settling the portion of p-nitroaniline (PNA) removal that can be attained by performing a photocatalytic degradation process (UV/ZnO). In order to evaluate the structural properties of nanoparticles, we have exerted the SEM, TEM, PL, DRS, and XRD analyzes. The highest efficiency for elimination of p-nitroaniline (94/4%) was achieved via the utilization of a photocatalytic degradation procedure (UV/ZnO) at the optimal pH of 7, 105 min contact time, at concentration of p-nitroaniline 10 mg/L, with an immobilized dose of 1 g/L for ZnO. The total organic carbon (TOC) removal has been ascertained under the optimal conditions (maximum 72.2%). Thus, the photocatalytic degradation procedure (UV/ZnO) is apparently a viable proposal for degrading the organic compounds from aqueous solution.
