Abstract
The work described in this study concerns the development of a disposable amperometric sensor for the electrochemicalcarbon electrodes (SPCEs) coupled with immobilised syringaldazine, commonly used as an indicator in photometric FACdetection, which was directly immobilised on the surface of SPCEs using a photopolymer PVA-SbQ. To enable in-fieldanalysis of FAC, a protype hand-held electrochemical analyzer has been developed to withstand the environment withits rugged design and environmentaly sealed connections; it operates from two PP3 (9 volt) batteries and is comparableM1cm2 and the detection limit for FAC was found to be 2.0M.
