{Abstract}: 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+.
