چکیده مقاله:
A simultaneous separation and pre concentration of Pb (II) ions from water samples for subsequent flame atomic absorption spectrometric determination was proposed. The procedure is based on sorption of Pb (II) at the buffering PH of 8, on a mini column(10cm length and 5mm internal diameter) filled with 0.7 g Amberlite XAD-16 resin impregnated with chelating agent of 1,4-diaminoantraquinone (DAAQ). After passing of sample solution from column, elution process was carried out with passing of 5 ml HCL 2M into column and then transferred to FAAS for determination. The sample and eluent flow rate, eluent concentration and ionic strength effect were investigated and optimized. RSD, LOD (3sb/m), recovery were fined to be 2.8%, 1.8Í10-9 M, 2.95% respectively
