Summary: The newly synthesized smart adsorbents used in this study are capable of selectively removing nickel [Ni(II)] ions from aqueous solutions with dual (pH and temperature) memory due to self-assembled recognition sites in the MIP structure. These smart cryogels demonstrate a maximum binding capacity for Ni(II) ions and achieve equilibrium adsorption within a short time frame, making them efficient and practical for water and wastewater treatment applications.

Summary: The nano-sized magnetic ion-imprinted polymers (MIIPs) synthesized using chitosan showed high sorption selectivity for Ni(II) and could efficiently recover the adsorbed ions. The sorption process was quick, endothermic, and could be described by Langmuir isotherm model and pseudo-second-order kinetic model. MIIPs proved to be a suitable adsorbent for selective removal and recovery of low-concentration Ni(II) ions from wastewaters.

Summary: Magnetic ion-imprinted microspheres were successfully prepared using reverse emulsion polymerization and effectively adsorbed heavy metal ions from sewage. The microspheres consisted of a core-shell structure with a semi-interpenetrating polymer network of cross-linked polyacrylamide and linear chitosan as the microgel shell, and magnetic particles enclosed in the shell. The adsorption capacity was further improved using ion imprinting technology. The study investigated the effects of the ratio of polyacrylamide to chitosan on the thermal stability, magnetic properties, and microstructure of the microspheres. The results showed that the microspheres exhibited excellent selective adsorption of Cu(II) and the adsorption mechanism was a combination of electrostatic interaction and ion exchange.
