Nickel Adsorption from Environmental Samples by Ion Imprinted Aniline -Formaldehyde Polymer
In this study, aniline-formaldehyde polymer was synthesized and then modified with extra aniline as cross-linker in the presence and absence of Ni(II) as the template to produce Ion Imprinted Poly(Aniline-Formaldehyde) (IIPAF) and Non Imprinted Poly(Aniline-Formaldehyde)(NIPAF) The IIPAF was subject...

| description | In this study, aniline-formaldehyde polymer was synthesized and then modified with extra aniline as cross-linker in the presence and absence of Ni(II) as the template to produce Ion Imprinted Poly(Aniline-Formaldehyde) (IIPAF) and Non Imprinted Poly(Aniline-Formaldehyde)(NIPAF) The IIPAF was subjected to adsorption, preconcentration and determination of Ni(II) ion in environmental samples. The effect of pH, contact time, interfering ions and other parameters on adsorption of Ni(II) was investigated.The optimum pH was found to be 8.0 with a recovery of 97.5%. Elution was performed with 0.5 M nitric acid. The sorption polymer capacity was found to be 59.4 mg.g-1. The concentration of the metal ion was detected with flame atomic adsorption spectrometry.The prepared ion imprinted sorbent showed high adsorption capacity, significant selectivity, good site accessibility and fast binding kinetics for Ni(II) ion. Scatchard analysis revealed that the homogeneous binding sites were formed in the polymers. The equilibrium adsorption data of Ni (II) on synthetic polymer were analyzed by Langmuir, Freundlich and Temkin models. The method was successfully applied for determination of Ni(II) ions in environmental water sample. |
