大气中还原态硫化合物的测定
DETERMINATION OF THE REDUCED SULFUR COMPOUNDS IN THE AIR

摘要: 建立了一套简便易行的还原态硫化合物的采集及分析方法,该方法可分离和检测11种还原态硫化合物.利用该方法测定了北京市和青藏高原地区还原态硫化合物的混合比,结果表明,北京市和青藏高原地区存在较强的COS和CS2人为和自然排放源.Abstract: A simple and reliable method for collection and analysis of reduced sulfur compounds was set up.Eleven sulfur compounds can be separated and detected in the system.The mixingratios of reduced sulfur compounds in Beijingcity and Tibetan highland were determined by usingthe method.The results indicated that stronganthropogenic and naturalsources of COS and CS2 existed in the two investigated areas.
