ABSTRACT To achieve efficient and selective removal of Cu 2+ from a multi‐ion coexistence environment, ‐imprinted SA/CMC/AM microspheres (IMSCA) were synthesized. The adsorption capacity efficiency the material under different preparation conditions investigated. surface morphology functional groups IMSCA characterized analyzed using SEM, FTIR, XRD. SEM images revealed relatively smooth with specific pores uniform structure. Special peaks appeared in FTIR spectrum IMSCA, indicating possibility imprinting process presence sites. semicrystalline structure exhibited by imprinted XRD characterization further reinforces likelihood In terms kinetics, followed pseudo–second‐order kinetic model, suggesting that chemical was dominant during process. isotherms, Langmuir model better fitted experimental data, monolayer adsorption. mixed solutions multiple metal ions. After 10 adsorption–desorption cycles, remained at approximately 90%. Compared other materials, exhibits higher capacity, faster elution rate, superior reusability.
