A new nanocomposite based on Cloisite 30B clay modified with ZnO and Ag2O nanoparticles (Cloisite 30B/ZnO/Ag2O) was synthesized as an effective catalyst in the sono-photocatalytic process of crystal violet (CV) methylene blue (MB) dyes simultaneously. The characteristics catalytic activity 30B/ZnO/Ag2O were investigated under different conditions. specific active surface for 18.29 m2/g. Additionally, showed that (CV: 99.21%, MB: 98.43%) compared to 30B/Ag2O 85.38%, 83.62%) 68.21%, 66.41%) has more activity. using had maximum efficiency at pH 8, time 50 min, amount 40 mM H2O2, dose 0.5 g/L, concentration 'CV + MB' 5 mg/L. can be reused up six steps. According results, •OH h+ degradation desired method. Data followed pseudo-first-order kinetic model. method used this research is efficient promising remove from wastewater.

CuMn2O4/chitosan micro/nanocomposite: Green synthesis, methylene blue removal, and study of kinetic adsorption, adsorption isotherm experiments, mechanism and adsorbent capacity

Arabian Journal of Chemistry, Год журнала: 2023, Номер 16(6), С. 104754 - 104754

Опубликована: Март 2, 2023

In this work, we choose a simple, green hydrothermal method for the fabrication of pure phase CuMn2O4 nanostructures in presence onion as capping agent, first time. next step, synthesized CuMn2O4/chitosan micro/nanocomposite. The structural analysis and composites showed their purity. results that prepared micro/nanocomposites have very efficient adsorption removing methylene blue. order to design analyze experiments were used response surface methodology (RSM). optimal conditions, pH value, adsorbent dose, initial concentration, contact time stirring speed obtained 6.5, 1.25 g/L, 1 mg/L, 5 min 500 rpm respectively. Kinetic isotherm investigate process mechanism capacity blue, value R2 (0.997) qe cal which was close exp, confirmed pseudo-first-order kinetic model. Langmuir model with qmax 54.05 mg/g described experimental data well. KL 0.06, range 0–1, means composite blue favorable. Moreover, present can be effectively up five adsorption/desorption cycles.
