Abstract
A water soluble conjugated polymer { poly [ 2, 5-bis ( sodium 4-oxybutyrate)-1, 4-phenylethyny-lene-alt-1,4-phenyleneethynylene], PPE-OBS}, was synthesized for the detection of picronitric acid(PA). PPE-OBS was characterized by means of mass spectrometry, NMR spectroscopy, infrared spectroscopy(IR), and so on. The experiment conditions and detection performance of PPE-OBS were systematically studied. The results show that the fluorescent quenching of PPE-OBS is the most efficient when the reaction time between PPE-OBS and PA is 20 min in the boric acid-sodium hydroxide buffer solution ( pH = 9. 5). The results demonstrate that PPE-OBS as a sensor for PA has a good linear range from 1. 0 to 60 μmol/ L with the calculated limit of detection(LOD) to be 0. 831 μmol/ L. Meanwhile, PPE-OBS paper was applied to rapidly detecting PA in environmental water samples.关键词
