Cloud point extraction is a separation and preconcentration procedure that has been
extensively applied for trace metal determination in several different matrices. Its major …

Cloud-point extraction (CPE), an easy, safe, environmentally friendly, rapid and inexpensive
methodology for preconcentration and separation of trace metals from aqueous solutions …

The investigation of a groundwater resource impacted with Cr (VI) requires analysis of
groundwater for Cr (VI) and total Cr. Most notably, Cr (III) is considered to be a trace element …

Chromium is introduced into the environment by effluents in several industries. It is important
to control this element since it is both toxic and carcinogenic. As its toxicity depends on its …

Recently, cloud point extraction (CPE) has been an attractive subject as an alternative to
liquid–liquid extraction. The technique is based on the property of most non-ionic surfactants …

A cloud point extraction procedure was presented for the preconcentration of copper, nickel
and cobalt ions in various samples. After complexation with methyl-2-pyridylketone oxime …

This review covers recent developments in surfactant-based extraction methods, with the
aim of highlighting some of the most important aspects of micellar systems together with their …
