Cloud point extraction and spectrofluorimetric determination of aluminium and zinc in foodstuffs and water samples

Cloud point extraction and flame atomic absorption spectrometric determination of cadmium(II), lead(II), palladium(II) and silver(I) in environmental samples

“…The small volume of the surfactant-rich phase obtained with this methodology permits the design of extraction schemes that are simple, cheap, highly efficient, fast, and of lower toxicity than those extractions that use organic solvents. The CPE method has important practical application and used to separate and preconcentrate analyte compounds as a step prior to their determination after the formation of sparingly water-soluble complexes [26][27][28][29][30][31][32][33].…”

Dispersive ionic liquid microextraction of aluminium from environmental water samples by effervescent generation of carbon dioxide

“…The analytical techniques which are mostly used for the determination of Al(III) are spectrofluorometry [6], graphite furnace atomic absorption spectrometry (GFAAS) [7], spectrophotometry [8] and flame atomic absorption spectrometry (FAAS) [9]. The separation techniques which are mostly used for the preconcentration of the analyte are solid-phase extraction (SPE) [10,11], liquid-liquid extraction (LLE) [12] and cloud point extraction (CPE) [13]. The GFAAS technique has been widely used for the quantification of Al(III), due to its high sensitivity and low sample volume [14].…”

On-line Flow-injection Liquid-phase Microextraction and Spectrophotometric Determination of Traces of Copper(II) with Trithia-9-crown-3 as Complexing Agent

“…To achieve these aims, various techniques, including liquid-liquid extraction (LLE), 16 cloud point extraction (CPE), micelle-mediated extraction, 17 membrane extraction (i.e., ultrafiltration and dialysis), 18 and solid-phase extraction (SPE), 19 have been developed for the extraction and preconcentration of various analytes. However, trends in analytical chemistry are the development of previous methods or introducing new techniques with improved selectivity, sensitivity and also miniaturization of chemical analysis methods.…”
