Analytical sonochemistry: A review

Abstract

Analytical chemistry is one of the chemical areas where ultrasonic radiation has been only infrequently used (namely in sample pretreatment, separations, automatic analytical systems and clinical analysis). This auxiliary technique would constitute a powerful aid in the automation of several steps in analytical processes: its advantages and disadvantages, as well as its use and potential in the area of non-invasive detectors, are reviewed in this paper.
