Chemiluminescence widely exists in our life.Because of its advantages of no excitation light source,small background interference and high sensitivity,it is widely used in clinical diagnosis,food detection,environmental monitoring and other fields.Luminol is one of the most commonly used liquid-phase chemiluminescence reagents.This popular science experiment uses liquid-phase chemiluminescence reagents-luminol and vitamin B2 as carriers,showing a gorgeous"fluorescent sea"under laboratory and home conditions,respectively.In the laboratory,copper wire,hydrogen peroxide solution,fluorescein and other simple raw materials were used to design various display schemes such as"magic summons","chemical reach","light up China"and"dynamic earth".Using vitamin B2,tonic water and other common items in life,the myste-rious fluorescence is no longer out of reach.It vividly embodies the concept of"chemistry is life".In the process of display,the contestant ob-serves from the phenomenon to the interpretation of the luminous mechanism,and then promotes the related life encyclopedia in the form of ani-mation,step by step.While conveying the beauty of chemistry,it conveys the concept of"community of human destiny".The popular science program closely links chemistry with life.It is green,safe,simple and attractive,and has strong operability and experience.
