Utilization of Synthesized Copper Ferrite/Calcium Alginate Nanocomposite for Adsorption and Photocatalytic Degradation of Malachite Green

In this article, the effectiveness of two different application methods (photocatalytic degradation and adsorption) onto the created solid nanomaterials for the removal of malachite green (MG) was investigated. Copper ferrite nanoparticles (CF) and copper ferrite/calcium alginate composite (CG) were synthesized as two studied solid samples. By using XRD, TGA, FTIR, DRS, nitrogen adsorption/desorption isotherm, pH(PZC), SEM, and TEM, the physicochemical and morphological properties of the solid samples were tested. Sample dose, pH, initial MG concentration, shaking time, ionic strength, UV light power, and temperature were the key experimental parameters that were established. The obtained results demonstrated that at 40 & DEG;C, CG reached a greater adsorption capacity (297.62 mg/g). The spontaneous, endothermic, and advantageous adsorption process of MG was proved by the best fitting of pseudo-second order, Elovich, intra-particle diffusion, Langmuir, Dubinin-Radushkevich, and Temkin models onto all the produced materials. The maximum percentage of MG degradation by CG (89.9%) was accomplished by utilizing 1.0 g/L of catalyst mass, an initial MG concentration of 10 mg/L, and 33 W. Arrhenius and Eyring-Polanyi models well applied the MG photodegradation onto the catalyst surface.

Automated summary

This study investigated the effectiveness of two different application methods (photocatalytic degradation and adsorption) for removing malachite green (MG) using solid nanomaterials. Copper ferrite nanoparticles (CF) and copper ferrite/calcium alginate composite (CG) were synthesized as the solid samples. Various physicochemical and morphological properties of the samples were tested. The experimental parameters included sample dose, pH, initial MG concentration, shaking time, ionic strength, UV light power, and temperature. The results showed that CG had a higher adsorption capacity (297.62 mg/g) at 40°C. The adsorption process of MG onto the materials was proven to be spontaneous, endothermic, and advantageous. The CG achieved a maximum MG degradation percentage of 89.9% under specific conditions.
