Open publisher page 0 citations

Abstract

Cloud point extraction has been used for the preconcentration of cadmium after the formation of a complex with dithizone and later analysis by graphite furnace atomic absorption spectrometer using Triton X-114 as surfactant.The best condition affecting the preconcentration process was chosen.This method can be successfully applied to the measurement of cadmium in water samples.Under the optimum conditions,the detection limit was 0.015μg/L for cadmium.
