Speciation of chromium in river water samples contaminated with leather effluents by flame atomic absorption spectrometry after separation/preconcentration by cloud point extraction
(Elsevier, 2009)
n the present work, a cloud point extraction (CPE) system has been proposed for determination of species de chromium in the natural water samples, Cr(III) and Cr(VI). The procedure was based on the reaction of Cr(III) with ...
Cloud point extraction and concentration of carbaryl from natural waters
(TAYLOR & FRANCIS LTD, 2009)
An improved procedure is proposed for determination of the pesticide carbaryl in natural waters based on double cloud point extraction. The clean up step was carried out only with Triton X-114 in alkaline medium in order ...
Environmental monitoring of phenolic pollutants in water by cloud point extraction prior to micellar electrokinetic chromatography
(Springer Heidelberg, 2009-05)
Many aromatic compounds can be found in the environment as a result of anthropogenic activities and some of them are highly toxic. The need to determine low concentrations of pollutants requires analytical methods with ...

Determination of mercury in biological samples by cold vapor atomic absorption spectrometry following cloud point extraction with salt-induced phase separation
(2007)
Method development for the pre-concentration of mercury in human hair, dogfish liver and dogfish muscle samples using cloud-point extraction and cold vapor atomic absorption spectrometry is demonstrated. Before the extraction, ...
Cloud point extraction of vanadium in parenteral solutions using a nonionic surfactant (PONPE 5.0) and determination by flow injection-inductively coupled plasma optical emission spectrometry
(Elsevier Science, 2002-10-16)
A preconcentration and determination methodology for vanadium at trace levels in parenteral solutions was developed. Cloud point extraction was successfully employed for the preconcentration of vanadium prior to inductively ...
