摘要
通过采用炭粉和二氧化碳在高温下反应获得一氧化碳、借助棉花、采用二氧化碳浓度传感器改进“一氧化碳还原氧化铁”实验,将一氧化碳的获取、一氧化碳与氧化铁反应、产物的检验和尾气的处理等进行一体化设计,使该实验演示可行化、可视化、安全化和环保化,突破传统教学难以演示的瓶颈。
This paper improves the experiment of“carbon monoxide reduction of iron oxide”by reacting carbon powder and carbon dioxide at high temperature,using cotton,and using carbon dioxide concentration sensors,integrates the acquisition of carbon monoxide,the reaction of carbon monoxide with iron oxide,product testing,and exhaust gas treatment into a unified design,making the experiment demonstration feasible,visual,safe,and environmentally friendly,which breaks through the bottleneck of traditional teaching demonstrations that are difficult to perform.
