dc.description.abstractCloud point extraction was employed as a pre-concentration method for the determination Of trace amounts of lead (Pb) after formation of a complex with (4-(2-pyridyi-azo)-resorcinol) (PAR) and later analysis by flame atomic absorption spectrometry (FAAS) using polkoxyethylene-7.5 octylphenyl-ether (Triton, X-114) as surfactant. After phase separation, based on the cloud, point separation of the mixture; the surfactant-rich phase was diluted with 1.0 mol L-1 HNO in methanol. The parameters affectmg the separation of the phases and the detection process were optimized. Under the optimum experimental conditions [i.e., pH 9.0, 2.0(-4) L-1 of PAR, 0.1% (w/v) Triton X-114 1 the detection limits were 2.1 and 1.6 ng mL(-1) for 30.0 and 40.0 mL solutions, respectively. The sensitivity of FAAS was improved by 31.0- and 43.7-fold for 30.0 and 40.0 mL of initial volumes, respectively. The developed method Was applied to the determination of lead in water samples with satisfactory results. The method was validated by employing certified wastewater CWW-TM-D and spiked/fortified water. NWTM-15.en_US
