COMPUTERIZED SYSTEM FOR DUAL-ELECTRODE MULTISWEEP CYCLIC VOLTAMMETRY FOR USE IN CLAY-MODIFIED ELECTRODE STUDIES

摘要

A computerized system for dual-electrode multisweep cyclic voltammetry has been developed. The system was designed to ensure clay film integrity (no stripping of clay) and to eliminate. exposure of the clay film to atmospheric drying or oxidizing conditions during electrolyte switching. Because of the control over electrode history, reproducible single clay film swelling and exposure studies may now be carried out. In addition, the kinetics of change in the film structure may be followed.
