TLDR
The cloud-point extraction process using micelle of the cationic surfactant CTAB to extract Fe3+and Pb2+ from aqueous solutions was investigated and the analytical characteristics of the method (e.g., limit of detection, linear range, preconcentration and improvement factors) were obtained.Abstract:
A cloud-point extraction process using micelle of the cationic surfactant CTAB to extract Fe3+and Pb2+ from aqueous solutions was investigated. The method is based on the color reaction of Fe3+and Pb2+ with bromopyrogallol red at pH 5.0 and micelle-mediated extraction of the complex. The optimal extraction and reaction conditions (e.g., surfactant concentration, reagent concentration and effect of time) were studied and the analytical characteristics of the method (e.g., limit of detection, linear range, preconcentration and improvement factors) were obtained. Linearity was obeyed in the range of 0.05-43.00 ng mL-1 of Fe3+ ion and 0.10-40.00 ng mL-1 of Pb2+ ion and the detection limit of the method was 0.020 and 0.040 ng mL-1 for Fe3+ and Pb2+, respectively. The interference effect of some anions and cations was also tested. The method was applied to the determination of Fe3+ and Pb2+ in vegetable (lettuce, spinach, cabbage, parsley, and dill), tea, rice, human hair, liver, and chicken and water samples.read more
