【 摘 要 】

A composite electrodeprepared by mixing a commercial epoxy resin Araldite® and graphitepowder is proposed to be used in didactic experiments. The electrode is preparedby the students and applied in simple experiments to demonstrate the effectof the composite composition on the conductivity and the voltammetric responseof the resulting electrode, as well as the response in relation to the scanrate dependence on mass transport. The possibility of using the composite electrodein quantitative analysis is also demonstrated.
