چکیده
a simple and sensitive method is described for the pre-concentration by cloud point extraction followed by atomic absorption spectrometric determination of copper ion in real samples. at a solution ph of 5.5, 5, 5-diphenylimidazolidine-2, 4-dione (phenytoin) (dfid) and tritonx-114 were used as hydrophobic ligand and non-ionic surfactant. the adopted concentrations for dfid, triton x-114 and hno3, bath temperature, centrifuge rate and time were optimized. detection limits (3sdb/m) of 1.7 ng ml-1 along with enrichment factors of 35 for these ions were achieved. the proposed procedure was applied to the analysis of real samples.
