Micelle mediated selective extraction of lead after its complexation with thionine in aqueous samples prior to FAAS determination

A micelle mediated phase separation and preconcentration process of trace level Pb (II) ions in water samples, after chelating with thionine for determination by flame atomic absorption spectrometry (FAAS) was developed. The preconcentration step was based on the cloud point extraction of lead-thion...
