Removing arsenic from industrial wastewater remains a crucial task. To protect public health and safety address environmental pollution, there is an urgent need for material that can efficiently remove wastewater. In this study, simple highly efficient adsorbent, namely, Co/Mn bimetallic-based organic framework (CoMn-MOF-74) was prepared by hydrothermal synthesis method. Experimental results demonstrate CoMn-MOF-74 exhibits excellent adsorption capacity ions in It found the optimal molar ratio of adsorbent 1:1. The compensates deficiencies performance Co-MOF-74 Mn-MOF-74, increasing rate highest capacity. maximum 93.4%, 531 mg/g. Fitting according to two categories models, specifically, isotherm kinetics indicated adheres Langmuir model pseudo-second-order kinetic model. process mainly chemical monolayer adsorption. Analysis XPS revealed metal–oxygen groups hydroxyl play important roles process. conclusion, shows prospects field promising arsenic-removing adsorbent.

Ni-Mn ferrites magnetic nanoparticles (MNPs) were successfully prepared through the ethanol solution combustion-calcination process, and characterized by SEM, TEM, XRD, VSM, BET, FTIR techniques. For smaller particle size suitable property, optimum element ratio of material was Ni 0.9 Mn 0.1 Fe 2 O 4 , optimal preparation conditions appropriate dosage to attain 3+ concentrations approximately 0.85 M, calcination temperature 400 °C, time h, their specific surface area 136.5 m /g, average saturation magnetization 35 nm 21.66 emu/g, respectively. The adsorption process methyl blue (MB) onto MNPs conformed pseudo-second-order kinetic model in initial 100–250 mg/L. In comparison with Langmuir Freundlich isotherm models, Temkin (R = 0.9865) observed better demonstrate state MB MNPs, revealing that mechanism multi-molecular chemical process. capacity for still maintained about 90% adsorbance after 6 times cyclic utilization recalcination method, suggesting had excellent regeneration performance. general, these results coupled its environmental friendliness attributed potential candidates effluent remediation.
