Abstract

This review addresses the use of cloud point extraction as a separation and pre-concentration method aiming at the speciation of metals and metalloids by spectroanalytical techniques. The principles, advantages and limitations of this technique are presented for a better understanding of its potential. The main strategies for using cloud point extraction in carrying out speciation analysis are discussed. To illustrate its applicability in the development of analytical methodologies aimed at speciation, some works found in the specialized literature are commented, highlighting their contribution to the theme. Finally, future trends for the development in this field (such as speciation of anionic species, cloud point micro extraction, speciation of nanoparticles, among others) is presented and discussed.
