Abstract
Electrochemical remediation of the environment is gaining widespread acceptance due to the mild conditions used, the cleanliness of the electron as a reagent, the easiness for automation, its versatility, etc. In this paper three phenomena are presented at the microscale level, originating from the application of an electric field to a simulated soil sample: a) Demonstration of metal ion migration, b) Demonstration of the creation and movement of an acidic and a basic front, and c) Demonstration of water movement through soil.

We have developed an experiment to demonstrate the removal of a metal from an insoluble surrogate soil pollutant, CuCO3·Cu(OH)2, by complexation followed by the ...
Electrochemical Removal of Metal Cations from Wastewater Monitored by Differential Pulse Polarography
Delphine Bruce , Alexander Kuhn and Neso SojicJournal of Chemical Education2004 81 (2), 255Electrochemical Removal of Metal Cations from Wastewater Monitored by Differential Pulse Polarography
Delphine Bruce , Alexander Kuhn and Neso SojicJournal of Chemical Education2004 81 (2), 255A simple experiment is described that exposes students to two important aspects of electrochemistry: its potential use in industrial technologies and its application for solving analytical problems. To illustrate these two points we have chosen to examine ...

J. G. IbanezJournal of Chemical Education2001 78 (6), 778Many polluting gases can be transformed to nonpolluting--or at least, less polluting--forms by changing the oxidation states of one or more of their constituent atoms. This can often be achieved by transferring electrons to or from the pollutant from or ...
