| Abstract | ||||
| A novel Vanadium(IV) ion-imprinted polymers (IIPs) was synthesized by bulk polymerization using different types of monomers such as1-vinyl imidazole and Styrene, respectively. molar ratios of template, monomer and cross-linking agent for polymerization, solvents and Various monomers were studied to obtain the largest adsorption capacity for Vanadium. The prepared Vanadium-IIPs were characterized using Fourier - transform infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDX) and Scanning electron microscopy (SEM). The process of elution has no influence on the three-dimension network structure surfaces of Vanadium-IIPs. Vanadium(IV) ions could be eluted from IIPs successfully by mixture solution from ethanol and acetic acid. The maximum adsorption capacity of vanadium-IIPs was is (568)µmol/g for Vanadium-IIP1(using styrene as a monomer) and (491)µmol/g for Vanadium-IIP2(using 1-vinyl imidazole as a monomer). The adsorption by Vanadium-IIPs followed a Langmuir isotherm models. Solid-phase extraction (SPE) syringe packed with ionic imprinted polymers (IIPs) were used to selective separation for Vanadium (IV) ion from Crude or fuel oil and digest the polymer to determination the Vanadium by flame atomic absorption spectroscopy (FAAS) Abbreviation IIP-SPE-FAAS | ||||
