Photodegradation of Methylene Blue with Aid of Green Synthesis of CuO/TiO2 Nanoparticles from Extract of Citrus Aurantium Juice

Green synthesis methods using plants have many advantages such as time-saving, chemical-free, and negative effects on the environment. So, extracted Citrus aurantium juice was used to synthesize green CuO/TiO2 and(G- CuO/TiO2) nanocatalyst which characterized by XRD, SEM, EDX, FTIR, BET, ZP utilized in degradation of methylene blue (MB) under UV lamps dark environments. The ANOVA program maximize photodegradation efficiency (%) (G-CuO/TiO2) MB dye. four independent variables: Initial dye concentration (10-50 mg/L), pH (3-9), adsorbent dose (200-1000 contact time (30-90 min) served model (%). results confirmed high significance regression while predicted values were good agreement with corresponding experimental ones. Optimized conditions for maximum (98.6%) (G- NPs initial (10.93 (8.87), mass (986.43 (89.08 min). validity quadratic examined, found values. Results demonstrated that could be a promising photocatalyst Copyright © 2023 Authors, Published BCREC Group.
