STYDY APPLICATION TECHNIQUES CLOUD POINT EXTRACTION AND METHOD ATOMIC ABSORPTION SPECTROMETRY (AAS) DETERMINATION TRACE AMOUNT OF ION METAL

Abstract

    Pollution of heavy metals (such as Pb, Cd, ...) caused serious effects to theenvironment and human health. Through the survey of optimal conditions of AASmeasurement as well as factors effecting the CPE techniques such as time,temperature, speed centrifugal separation phase, reagent concentration,concentration of buffer solution, viscosity, surfactant, ... By combining technicalcloud point extraction (CPE) and method atomic absorption spectrometry (AAS) todetermine trace amounts of Pb, Cd in water. The recovery of metals is determinedafter the analysis process.

Keywords: Cloud point extraction, atomic absorption spectrometry, Pb, Cd.1.
