摘要：A sensitive cataluminescence (CTL)-based gas sensor using nano-sized Y2Ti3O9 as a probe was proposed for the determination of trimethylamine (TMA) in air. The gas sensor showed high selectivity for TMA at 490 am and satisfying activity at 320 degrees C. The linear range of the CTL intensity versus concentration of TMA was 1 similar to 70 mg/m(3) (gamma = 0.995), and the detection limit (3 sigma) was 0.6 mg/m(3). No interference was observed while the foreign substances, such as ammonia, ethanol, benzene, carbon monoxide and sulfur dioxide, were passing through the sensor. The gas sensor displayed good stability for continuously introducing TMA over 100 h, and allowed on-line monitoring of TMA in air.
