Polluted environments often contain large amounts of toxic metals, such as cadmium, which pose a major threat to ecosystems and public health. Contamination by cadmium its compounds is observed in areas surrounding zinc mining sites electroplating factories, the control pollution essential for environmental safety In this study, highly efficient straightforward separation strategy K4Fe(CN)6@Fe3O4 nanocomposites successfully developed capture Cd ions water environment. Batch adsorption experiments revealed that exhibited high removal rate (greater than 98 %) at pH level 6.0 solid-liquid ratio 1.0 g/L room temperature (298 K). Kinetic analysis process followed pseudo-second-order model was rapidly removed first 10 min, with chemisorption dominating Cd2+ K4Fe(CN)6@Fe3O4. Adsorption isotherms heterogeneous behavior, maximum capacity 40.78 mg/g. The intrinsic occurring primarily through electrostatic interaction ion exchange. addition, an excellent regeneration capacity. Therefore, integrating Fe3O4 into metal cyanide not only provided composite material chemical stability selective Cd2+, but also facilitated subsequent sorbent collection recovery. Overall, study presents simple feasible approach potassium ferrocyanide frameworks from contaminated water.
