Sonoelectroanalysis - Application to lead determination

Abstract

Ultrasound and benefits of its application in electrochemistry and electroanalysis have been explained and demonstrated. Lead determination by stripping analysis coupled with insonation was used to illustrate advantages of employing ultrasound in electro-analysis. Quantitative analysis of lead under insonation was shown to be possible in different media, including organic and biological samples where electroanalytical techniques often fail to give satisfactory results due to passivation of electrodes in these complex matrices.
