Abstract
The purpose of this article is to review and evaluate cloud point extraction of metals and its coupling to different contemporary instrumental methods of analysis This review covers a selection of the literature published on this topic over the period mainly between 1997 and September 2005 consisting of 50 publications The current state of the art for CPE concerning metals and metal chelates is presented with special emphasis on the hyphenation of this interesting extraction/preconcentration approach mediated by surfactants to spectrophotometry atomic spectroscopy and separation techniques We present contemporary CPE developments concerning metal speciation and determination and their application to different environmental clinical geological and food samples Strategies for method development as well as future perspectives are also covered
