Development of a cloud point extraction-spectrofluorimetric method for trace copper(II) determination in water samples and parenteral solutions

Cloud point extraction preconcentration and spectrophotometric determination of copper in food and water samples using amino acid as the complexing agent

“…CPE has been widely used to separate and preconcentrate organic compounds and metal ions (Paleologos et al, 2005;Bezerra et al, 2005;Silva et al, 2006). The use of CPE as a preconcentration step for the determination of Cu by spectrophotometry, spectrofluorimetry, flame and graphite furnace atomic absorption spectrometry have also been reported (Lemos et al, 2006(Lemos et al, , 2007Hassanien et al, 2007;Tabrizi, 2007;Chen et al, 2007;Ghaedi et al, 2008).…”

Development of a cloud-point extraction method for copper and nickel determination in food samples

“…The obtained detection limits by the proposed procedure are comparable to most of those reported in the literature. Due to good analytical characteristics, the proposed CPE procedure has been demonstrated to be very interesting for trace copper and nickel analysis [34][35][36][37][38][39][40][41][42][43].…”

Determination of Zinc, Copper, and Mercury in Water Samples by Using Novel Micro Cloud Point Extraction and UV-Vis Spectrophotometry

“…In spectrophotometric determination of analytes, it is common to use macrocells (3.5 mL). That means the consumption of diluting agent which is necessary to dissolve the micelles before introducing the sample to any instrument, can reach up to 2 mL [42].…”
