Abstract:
In search of a better primary treatment of acute boric acid poisoning, the adsorption capacity of boric acid onto activated carbon as an antidote was investigated in vitro.
Wide differences in the amount of boric acid adsorbed were recognized depending on individual activated carbons. In order to elucidate the dominant factor in boric acid adsorption, correlations between the properties of activated carbon and the amounts of boric acid adsorbed are discussed. A significant correlation was recognized between the surface pH of activated carbon and the amount of boric acid adsorbed in low equilibrium concentration. It is assumed that the surface pH of activated carbon is a chief factor affecting the amount of boric acid adsorbed.
