问 :电导法测定碳有何特点 ?——广东读者　　张宇　　　　答 :钢铁等金属材料试样经高温燃烧氧化使试样中的碳转化为二氧化碳 (气态 )而释出。如试样含硫 ,则硫同时转化为二氧化硫气体。用电导法测定时 ,将所释出的二氧化碳气体经过除硫管除去二氧化硫后导入一特定的电导池中 Q: What are the characteristics of the conductivity method for the determination of carbon? - Zhang Yu, a reader in Guangdong: Steel and other metal materials by high temperature combustion of the sample combustion of carbon into carbon dioxide (gaseous) and release. If the sample contains sulfur, the sulfur is simultaneously converted to sulfur dioxide gas. When measured by the conductivity method, the released carbon dioxide gas is passed through a sulfur removal pipe to remove sulfur dioxide and then introduced into a specific conductivity cell
