  • Publication number: 20200114189
    Abstract: The present invention relates to a method of detoxifying a liquid chemical agent using a metal organic framework having a surface modified with a basic amine-based compound. More particularly, a surface-modified metal organic framework having the amine-based compound deposited on a surface thereof and in pores thereof or bonded to the inside of a frame is prepared, and when the surface-modified metal organic framework comes into contact with the liquid chemical agent, a reaction with moisture in the atmosphere occurs, thus removing the liquid chemical agent through a hydrolysis reaction. It is possible to simultaneously detoxify various chemical agents such as a nerve agent and a vesicant, thus assuring a high detoxification effect on liquid chemical agents at room temperature even when using a small amount thereof.
