ADSORBENT FOR ORGANIC CHLORINE COMPOUND

摘要

PURPOSE: To obtain an adsorbent for removing an org. chlorine compd. in an aq. soln. CONSTITUTION: This adsorbent is a carbon compd. having <=0.1meq/g acidic functional group existing on the surface. Since the amt. of acidic functional groups is reduced and pore distribution is made optimum, adsorption sites of a large specific surface area peculiar to activated carbon are effectively utilized and the diffusion of an org. chlorine compd. in pores in water can be improved. As a result, the useful life of this adsorbent at the time of adsorbing and removing an org. chlorine compd. in water can be considerably prolonged.
