摘　　要：通过定性和定量两方面的探究,比较了饱和石灰水、氢氧化钠、氨水、碳酸钾、乙醇胺和N-甲基二乙醇胺等常见试剂捕集CO_(2)的效果。通过实验,探讨了CO_(2)捕集的速率和平衡问题,同时比较了上述CO_(2)捕集剂的捕集效果。该实验装置简单、试剂易得、现象明显,可作为课堂演示实验或学生综合实验。Through qualitative and quantitative exploration,the effectiveness of common reagents such as saturated lime water,sodium hydroxide,ammonia water,potassium carbonate,monoethanolamine,and N-methyldiethanolamine in capturing CO_(2) was compared.Through experiments,the rate and balance of CO_(2) capture were explored,and the capture effects of the aforementioned CO_(2) capture agents were compared.The experimental setup is simple,the reagents are readily available,and the phenomenon is obvious.It can be used as a classroom demonstration experiment or a student comprehensive experiment.
