| Abstract: | The dye palladium-meso-tetra (p-sulfonatophenyl) porphyrin (Pd-TSPP) has been bound to Dowex 1×2-200 resin by the electrostatic interaction. The resulting material could be extremely quenched by oxygen and is a useful probe for the measurement of oxygen in gas sample. The photochemical properties and the analytical performance of the room-temperature phosphorescence (RTP) probe have been studied by using gas flow-injection analysis (gFIA) system, which incorporates a convenient exponential dilution chamber for gas sample introduction. It was shown that the sensor has rapid response (Typical response times were 18s from N2 to O2 stream and 54s from O2 to N2 stream for 95% signals change), high precision (1.3% at 0.6% (V/V) O2 level) and low detection limit (0.65% (V/V) O2). |
