characterization of chemically modified carbon black for sorption application

The Use of New Chemically Modified Cellulose for Heavy. Differences between the surface chemical properties of hydrogen- and nitrogen-treated samples of an activated carbon were quantified using several complementary techniques. Calorimetric studies conducted at 303 K revealed that the sample treated in N2 at 1223 K adsorbs a great deal of oxygen with unusually high differential heats. In fact, both the quantity and the heat of adsorption increased, El-Shafey, E.I., Ali, S.N., Al-Busafi, S., Al-Lawati, H.A.
