摘要：A cataluminescence (CTL) based method for simultaneously identifying and determining formaldehyde (HCHO) and sulfur dioxide (SO2) in air was proposed. The experimental conditions meeting the algebraic sum rule of the CTL intensities of HCHO and SO2 were sought. They are two analysis wavelengths of 460 nm and 580 nm, the surface temperature of sensing materials of 280 degrees C and the flow rate of air of 130 mL/min. The limits of detection of this method were 0.08 mg/m(3) for HCHO and 0.6 mg/m(3) for SO2. Common coexistence matters, such as acetaldehyde, ammonia, benzene, ethanol, hydrogen sulfide and carbon dioxide, did not disturb the determination.
