| Abstract: | A new method for the determination of trace amount of lead by flame atomic absorption spectrometry with cloud point extraction was proposed.Lead was complexed with PMBP in an acidic medium using Triton X-100 as surfactant and quantitatively extracted into a small volume of the surfactant-rich phase after centrifugation.The effect of experimental conditions such as pH and concentration of reagents on cloud point extraction and determination sensitivity was discussed.The chemical variables affecting the separ... |
