摘要：

The immersion enthalpies are determined in benzene and water for eight activated obtained carbons from peach seed by thermal activation with CO2 to different temperatures and times of activation. The results obtained for these immersion enthalpies in benzene and water, present values between -4.0 and -63.9 Jg(-1) and -10. 1 and -43.6 Jg(-1) respectively. From nitrogen adsorption isotherms the textural parameters of the activated carbons are obtained: surface area, micropore volume and pore average diameter, which relate to the immersion enthalpies, obtaining directly proportional trends for the two first. The activated carbons are microporous and with character hidrophobic.
