“…The common method for the preparation of ion‐imprinted polymeric materials includes complex formation between the target ionic species and an active polymerizable ligand followed by polymerization in presence of an appropriate cross‐linker agent. The metal ions are then extracted from the cross‐linked polymeric network to leave recognition sites capable of selectively interacting with the same metal ions over the other interfering ones 25‐29 …”

Selective metal ions’ extraction and recovery has various applications in the analytical field. Metal ions need to be extracted, detected, and quantified. For that purpose, ion‐imprinted polymers have earned a great deal of attention during the past two decades. Pd2+ ion‐imprinted hollow silica particles including an isatin Schiff base were prepared by Schiff base condensation of (3‐aminopropyl)triethoxysilane and isatin. The prepared Schiff base ligand was coordinated to the target Pd2+ cations, the polymerizable Pd‐complex was set aside to form gel in the company of tetraethoxysilane and the target Pd2+ cations were subsequently removed from the cross‐linked silica network by means of acidified thiourea solution. All materials throughout this synthesis process were investigated utilizing mass spectrometry, elemental analysis, FTIR, and 1H‐NMR. The morphological structure of both Pd2+ ion‐imprinted and non‐ion‐imprinted silica polymer were pictured by scanning electron microscopy. Several batches were studied exploiting both Pd2+ ion‐imprinted and non‐ion‐imprinted silica polymer to test their functionality for selective extraction of Pd2+ cations in multi‐ionic solution of Ni2+, Co2+, Cu2+, Mn2+, and Pd2+.
