“…In the literature, there are several material used to create cross‐linked network for ion‐imprinting, for instance, Francisco et al 30 used 4‐vinylpyridine as polymerizable agent, ethylene glycol dimethacrylate as the crosslinking agent, and benzoyl peroxide for radical generator. Kumar et al 31 and da Santos Silva et al 32 utilized 1‐vinyl imidazole as ligand and methacrylic acid as functional monomer for synthesis of ion‐imprinted polymer. Biswas et al 33 used modified curcumin as functional monomer, ethylene glycol dimethacrylate as a binding agent and 2,2‐azobisisobutyronitrile as a free radical initiator.…”

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+.
