Enrichment and Determination of Lead (II) Ions in Natural Waters, Mineral Waters and Waste Waters by Micellar Mediated Extraction

In this study, the optimum conditions were determined mainly for the preconcentration of lead ions by cloud point extraction (CPE) method and their determination by flame atomic absorption spectrophotometer. In this developed method, Pb (II) metal ions were preconcentrated and determined by the cloud point extraction, which is a surfactant-based method, by complexing them with vitamin B6, which is a potential complexing agent. In the method, solution pH, surfactant and vitamin B6 concentrations, foreign ions, equilibrium time and temperature, sample volume parametres were optimized. Limit of quantication (LOQ) and limit of detection (LOD) values of the developed method were found to be 7.9 and 26.0, respectively. The validation of the optimized method was carried out by standard reference material analysis and the method was successfully applied to some real water samples such as natural spring waters wastewater and mineral waters.
