Resumen

BOHORQUEZ, Natalia; GIRALDO, Liliana  y  MORENO-PIRAJAN, Juan C. Immersion Enthalpies of Activated Carbon in  Carbamazepine Serum Solutions. Inf. tecnol. [online]. 2008, vol.19, n.1, pp.105-118. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642008000100013.

The immersion enthalpy and the adsorption capacity of activated carbon in carbamazepine serum solutions are determined in this study. The activated carbon were modified with nitric acid solutions of 40 and 65% at 303 K, increasing the content of the total acid sites on the surface.  ¶Relations between the superficial area and the immersion enthalpy variation in function of modification treatment and the adsorbed amount of carbamazepine. It was observed that for solids obtained from mineral coal, the interaction is influenced by the physical and chemical surface characteristics, while for solids obtained from the commercial activated carbon it was observed a greater interaction as the content of acid groups increases. ¶The activated carbons with higher carbamazepine adsorption are: the modified mineral activated carbons, CAmi40, CAmi65 and the commercial carbon modified with nitric acid with a higher concentration, CAmk65.

Palabras clave : immersion enthalpy; activated carbon; carbamazepine, acid modification.
