Сорбція іонів важких металів активованим вугіллям, одержаним хімічною активацією кизилової кісточки
Active carbons with high porous characteristics (SBEТ = 980–2100 m2·g-1, V? = 0.45–1.0 сm3·g-1) from dogwood stone have been obtained by chemical activation with phosphoric acid. Optimum impregnation coefficients (Xp= 1.0–1.25) have been found. Their sorption activity obtained against heavy metal io...

Chemistry, Physics and Technology of Surface| Резюме: | Active carbons with high porous characteristics (SBEТ = 980–2100 m2·g-1, V? = 0.45–1.0 сm3·g-1) from dogwood stone have been obtained by chemical activation with phosphoric acid. Optimum impregnation coefficients (Xp= 1.0–1.25) have been found. Their sorption activity obtained against heavy metal ions (Cd2+, Сr3+, Ni2+, Сu2+, Zn2+) has been investigated. By adsorption of ions an activity rank has been defined. It was observed that maximum adsorption becomes apparent concerning Сd2+, Cu2+, and Zn2+ ions. |
