Paper Abstract

The properties of polymer track membranes as a support for preparation of optrode are presented. Polyethyleneterephthalate membranes with 0.2 and 1 micrometers pores were used. The polymer foil with controlled pore size is additionally covered with poly(vinyl chloride) in order to immobilize the indicator inside the pores. The absorbance of the indicator used (N,N'-diphenylbenzidine) depends on the redox potential. The influence of different addition of covering polymer and different pore size on time characteristics of the optrode are described.
