Voltammetry of Electroactive Species at the Interface in Langmuir-Blodgett Trough

Abstract

In this study we propose a technique to increase the sensitivity of voltammetric determination of cadmium(II) ions and pesticide parathion. This is achieved by a method of horizontally touch voltammetry at the interface in a Langmuir-Blodgett trough.

Various approaches of achieving an increased concentration of the analyte at the interface that precede voltammetric measurements are discussed.
