Determination of Redox Potential (Eh) by Depolarizing Curve Method
Redox potential as an index of the intensity factor of the oxidation-reduction status of a soil has long been widely used in soil research. But in recent years it has been known that the true equilibrium potential is very difficult to be determined rapidly(l). Although attempts such as selection of electrode materials and treatment of electrode surface have been made, the problem has not been solved as yet. Therefore, it is nacessary to search for other measuring ways, if an accuracy of several milivolts is required.
