A series of crosslinked poly(2-hydroxyethyl methacrylate) films containing 1,2-diaminoantraquinone (DAQ) have been synthesized and characterized spectroscopically by FT-IR and UV-vis. Their response towards nitrite anion in acidic medium has been evaluated by means of time-resolved UV-vis spectroscopy. This kinetic analysis has provided a tool for the dynamic characterization of nitrite-sensitive films which could have application in biomedical analysis (nitrite monitoring of biological fluids) and environmental science (control of nitrite levels in drinking water).
