The current study aimed to the preparation of graphene oxide impregnated chitosan– polyvinyl alcohol hybrid beads (GO/CS-PVA) for removal Reactive Black 5 (RB5) dye from wastewater solutions, presenting them as a cost-effective alternative treatment. These were fabricated using dripping technique in an aqueous solution. surface and structure material before after adsorption process studied by analyzing FTIR spectroscopy Scanning electron microscope (SEM) well capacity was also evaluated. results proved successful synthesis GO/CS-PVA elucidated physical mechanism RB5. SEM images revealed uniform spherical with rough surface, approximately 752 μm diameter. Additionally, evaluation showed that optimum condition RB5 is at pH = 3 while kinetic investigations adhered pseudo-second-order model, indicating chemisorption reaction. Furthermore, increase temperature 25 65 °C enhanced maximum 34%. cytotoxic effect measured on adipose derived stem cells via MTT assay negligible. In conclusion, it eco-friendly adsorbents can efficiently remove practical applications.

This study details the synthesis and application of magnetic copper ferrite (CuFe2O4) nanoparticles for efficient removal acid red 88 crystal violet dyes from aqueous solutions. Utilizing a combustion method, were synthesized with succinic malic acids as fuels, yielding samples crystallite sizes 28.54 ± 0.90 nm sample 19.79 0.75 acid. Optimum conditions found at pH 2 10 violet, contact time 80 min an adsorbent dosage 0.05 g in 100 mL solution. Under these conditions, using achieved sorptive capacities 452.49 mg/g 446.43 while reached 408.16 374.53 mg/g, respectively. Both adsorption processes followed pseudo-second-order kinetic model aligned Langmuir isotherm. Thermodynamic analysis confirmed process exothermic spontaneous. Practical trials demonstrated efficiencies above 95% both real wastewater samples, underscoring method's practical potential water purification applications.
