Abstract
In this study, a new copper(II) ion-imprinted polymer (Cu(II)-IIP) was synthesized by the precipitation method. Itaconic acid, ethylene glycol dimethacrylate and 2,2′-azobisisobutyronitrile were used as functional, cross-linking monomer and a free-radical initiator, respectively. This polymer has been characterized on the basis of Fourier transform infrared spectroscopy and surface area measurements. The imprinted Cu(II) ions were completely removed from the polymer by leaching with the mixture of 0.1 M EDTA and 1 M HCl. The optimum pH for the adsorption of Cu(II) on to the polymer was 6. The selective performance of the polymer was compared to non-imprinted polymer (NIP) for the binary mixture Cu2+/Ni2+ and Cu2+/Zn2+. The relative selectivity of Cu(II)-IIP was 12.8 and 32.4 times greater than that of NIP as compared with the Zn2+ and Ni2+ ions, respectively. At optimal pH value, the maximum static adsorption capacity of Cu(II)-IIP and NIP was found to be 14.8 and 4.08 mg/g, respectively.
Highlights
Copper is a common environmental pollutant, which is encountered with food and drink in urban countries
It is really important to control the concentration of Cu in body fluids as well as environmental samples, which is usually accomplished by atomic absorption spectroscopy, inductively coupled plasma optical emission spectroscopy and inductively coupled plasma mass spectrometry methods
The aim of this work was the synthesis of a copper(II) ion-imprinted polymer, which applied in the solid-phase extraction system, can selectively adsorb copper(II) ions from the samples of a complex matrix, including biological and environmental samples
Summary
Copper is a common environmental pollutant, which is encountered with food and drink in urban countries. The basic principle of SPE is the transfer of analytes from the aqueous phase to the active sites of the adjacent solid phase, which is stimulated by the selection of appropriate optimal conditions in the system of three major components: water (liquid phase); analyte; and, sorbent [16]. It seems that among the methods of solid-phase extraction those where copper(II) ion-imprinted polymers were used were relatively simple to perform [17]
