Abstract
Abstract Purpose of this study is to report the green synthesis of a visible light driven photocatalyst Zincoxide incorporated Nanocellulose (ZnO/NC) from Tinospora Cordifolia plant stem extract and Sugarbagasse for the photodegradation of Enrofloxacin (EF), an antibiotic widely used in the veterinary medicines to treat animals for bacterial infections. By incorporating nano zinc oxide (ZnO) with NC, the band gap was enhanced to visible region. Thus the degradation of the EF was achieved under the visible light. Photo degradation was due to electron hole interaction. The photocatalyst ZnO/NC was characterized using FTIR, XRD, SEM and TEM. Various parameters such as the effect of pH, illumination time, amount of catalyst loaded and initial antibiotic concentration for the photodegradation of antibiotic EF was investigated. The optimum pH was found to be 5 and dose of the ZnO/NC was optimized as 0.20 g/L. Equilibrium was attained at 120 min and achieved a maximum degradation efficiency of 97%.
