Abstract
An efficient solid phase extraction method has been demonstrated for the removal and preconcentration determination of Cu (II), Co (II), Mn (II) and Cd (II) by using a new adsorbent material, alumina modified polyethylene glycol (PEG) nanocomposite (PEG-Al2O3). Flame atomic absorption spectroscopy (FAAS) was used to determine the concentration of metal ions adsorbed by PEG-Al2O3. Physically adsorbed metal ions from PEG-Al2O3 were eluted by using hydrochloric acid and the resultant solution was tested by FAAS. Various adsorption conditions such as effect of pH, amount of adsorbent, preconcentration time, elution time, volume of aqueous phase, and concentration of metal ion were optimized. High metal up-take was found providing this order: Cu (II) > Co (II) > Mn (II) > Cd (II) due to the strong contribution of surface loaded polyethylene glycol. Metal ions, (Cu (II), Co (II), Cd (II) and Cd (II)) containing four real samples (sea water, river water, tap water and grape juice) were studied. To our delight, the prepared PEG-Al2O3 nanocomposite was worked well towards the removal of metal ions with an excellent recovery percentage of 98-100%.
