VOLTAMMETRIC STUDY OF ION-EXCHANGE PROPERTIES AND OXYGEN PERMEABILITY OF THE MATERIALS FOR SOFT CONTACT LENSES
Abstract
The techniques of the voltammetric determination of oxygen permeability and of the activity in acid-base exchange were developed for the soft contact lenses. In the first case it is proposed to use the cathodic voltammetry by means of O2 reduction current in the airtight cell with a gold electrode. In the second case the authors suggest measuring the hydrogen oxidation peaks with platinum electrode during the absorption of free acid by lens material.
