Photocatalytic degradation of hexavalent chromium and different staining dyes by ZnO in aqueous medium under UV light
In this study, ZnO catalyst were synthesized using zinc nitrate and Terminalia arjuna bark
extract under microwave irradiation. This ZnO catalyst prepared through phytochemical
route was characterized by UV–Vis spectra, FTIR, XRD, XPS, TG/DSC, FE-SEM, and BET
specific surface area. The photocatalytic degradation of Cr (VI) and dyes viz., toluidine blue
o (TBO), safranin o (SFO) and calcon carboxylic acid (CCA) in aqueous solution was carried
out using ZnO catalyst under UV light irradiation (250 W). The XPS of ZnO used for Cr (VI) …
