An Eco –friendly approach towards removal of industrial dye using green synthesized zinc oxide nanoparticles immobilized in to sodium alginate beads |
| 초록 |
A green, eco-friendly approach for the synthesis of zinc oxide nanoparticles using Prunus x yedoensis leaf extract as reducing agent. Initial verification of ZnO NPs production was done by visual observation and measuring surface plasmon spectra at 436 nm. The synthesized ZnO NPs was characterized by HR-TEM, XRD, EDS, FTIR and zeta potential. The catalytic potential of Prunus x yedoensis leaf extract, zinc ion, synthesized ZnO NPs, commercial grade ZnO NPs and a Prunus x yedoensis leaf extract and ZnO NPs immobilized on sodium alginate hydrogel beads (SA HGB) were analyzed. The ability of these immobilized materials to remove methylene blue was investigated. Commercial grade ZnO NPs immobilized with SA HGB 0.5 g/20 mL were observed to have good catalytic activity followed by a mixture of synthesized ZnO NPs immobilized with SA HGB and Prunus x yedoensis leaf extract immobilized with SA HGB at 1.0 g/20 mL. |
