| Abstract | In this paper a novel solid phase extraction method to determine Cu (II), Co (II), Mn (II) and Cd (II) using Alumina– Polyethylene Glycol (PEG) as a new adsorbent is described. The method is based on the adsorption of copper, cobalt, manganese and cadmium ions in alkaline media on polyethylene glycol–alumina in a batch method, elution with mineral acid (hydrochloric acid) and determination by Flame Atomic Absorption Spectrometry (FAAS). The adsorption conditions such as effect of pH, amount of adsorbent, preconcentration time, elution time, aqueous phase volume and metal ion concentration were optimized in order to achieve highest sensitivity. The calibration graph was linear in the range of 2.0–100.0 ngmL−1 for Cu (II), 0.5–200.0 ngmL−1 for Co (II), 0.5-300 ngmL−1 for Mn (II) and 1-300 ngmL−1 for Cd (II) in the initial solution. The method was applied to determine Cu (II), Co (II), Mn (II) and Cd (II) in sea water, river water, tap water, metal alloy and grape juice samples. |
