Abstract
The application of hybrid sensor array based on pyrrole-substituted porphyrin electropolymers for simultaneous optical and electrochemical analysis of diazo-conjugated dyes of Sudan family is presented. Sudan colorants are widely used in many areas but accurate screening of their consumption is required due to the high toxicity. Thanks to the inherent electrochemical activity of Sudan dyes, as far as the intense coloration, it was possible to find the appropriate conditions of hybrid optical and electrochemical porphyrin electropolymer based sensor array system application for fast and simple monitoring of such analytes.
