前言一氧化碳是一种普遍存在的大气污染物,也是主要监测指标之一。其监测方法的研究,已有几十年的历史。随着分析化学、电子学的发展,监测方法的灵敏度、准确度不断提高。由重量法、容量法、分光光度法、电化学法发展到气相色谱法、红外线法。灵敏度由千分之几提高到 ppm 级。近几年,由于大气污染监测要求测出 ppb 级水平,以便开展大气本底的调查。不少大气污染研究工作者,在气—固反应的原理上作了许多工作。气—固反应具有响应快(几秒钟)、操作简单、携带方便、样品用量少、灵敏度高等 Preface Carbon monoxide is a ubiquitous atmospheric pollutant and one of the major monitoring indicators. Its monitoring methods of research, has decades of history. With the development of analytical chemistry and electronics, the sensitivity and accuracy of monitoring methods are continuously increasing. By gravimetric method, volumetric method, spectrophotometry, electrochemical method developed to gas chromatography, infrared method. Sensitivity increased from a few thousandths to ppm level. In recent years, the ppb level has been required for air pollution monitoring in order to conduct atmospheric background surveys. Many air pollution researchers have done a lot of work on the principle of gas-solid reaction. Gas-solid reaction with fast response (a few seconds), simple operation, easy to carry, less sample, high sensitivity
