Magnetic copper ferrite nanoparticles, CuFe2O4-NPs (CFN) were synthesized via a facile sol-gel method for the effective removal of 4-nitrophenol (4-NP) and indigo carmine dye (IC) as typical hazardous organic pollutants from wastewater. The texture, morphology, composition CuFe2O4 NPs thoroughly explored by various physicochemical techniques. Various factors affecting adsorption including effect adsorbent mass, contact time, pH, initial IC concentration, temperatures investigated to determine optimum conditions removal. impact diverse species other coexisting dyes on capacity CFN was investigated. Five isotherms using two-parameters (Tekman, Langmuir, Freundlich) three-parameters (Sips, Redlich-Peterson) models. exhibited maximum 57.4 mg/g according Sips model, with optimal observed at pH 3, time 90 minutes, an mass 0.1 g. Thermodynamic data revealed both endothermic nature random arrangement molecules onto adsorbent. elimination mechanism elucidated. Furthermore, CFN-catalyzed reduction NaBH4 followed first-order kinetics high rate 0.4365 min-1, reflecting catalytic CFN. magnetic features, cost-effectiveness, recyclability, activities towards 4-NP removals made promising catalyst wastewater remediation.

Abstract Ceramic membranes are gaining rapid traction in water and wastewater treatment applications due to their inherent advantages, such as chemical/thermal stability, low fouling propensity, extended lifespan. This review paper provides a comprehensive overview of ceramic membranes, exploring composition, fabrication techniques, filtration principles, diverse applications. Various types including alumina, zirconia, titania, silica, zeolite, discussed. As global challenges related scarcity pollution intensify, the implementation offers sustainable effective approach for safeguarding vital resources. Despite dominance polymeric field, constant pursuit reduced production costs apparent benefits membrane fueling growth. The also examines that demonstrate effectiveness pressure-driven technology treating industrial wastewaters from industries, textile, pharmaceutical, petrochemical. While shows efficiency various scenarios, future research should focus on optimizing investment through new technologies, improving selectivity, permeability, packing densities, minimizing fouling, proposing scale-up strategies based experimental results. collective findings reveal potential revolutionize environmental remediation.
