| Abstract: | Proposed method for determination of trace amounts of lead is based on solid phase extraction of metal ion by
2-aminothiazole group incorporated into a matrix of polystyrene-divinylbenzene (PS-DVB). Effect of pH, equilibration rate,
sorption and desorption of metal ions, effect of flow rate and effect of diverse ions were studied. Maximum sorption capacity
observed for Pb (II) was 0.29 mmolg⁻¹ at pH 5.5. Calibration range was linear up to 5 μg ml⁻¹ (R² =0.997) with a detection limit
of 25.0 μg l⁻¹. Pb (II) recovery at 97.5% confidence level was found to be 97.5 ± 2.1%. |
