<p>PURPOSE:To obtain an NO2 removing agent capable of being industrially, inexpensively and easily produced and removing NO2 at the normal temp. by adding an amino compd. having primary amine and an amino compd. having secondary amine to activated carbon. CONSTITUTION:An amino compd. having primary amine such as ethyleneamine and an amino compd. having secondary amine such as ethylamine are added to activated carbon of coconut husk in a wt. ratio of 10% or less. Since the amino compds. are chemically reacted with NO2 adsorbed into the pores of the activated carbon, NO2 can be removed. Thus, the removing agent removing NO2 in air can be easily produced in low cost.</p> |
