摘要：

Adsorption of naphtoic acid was investigated as a initial stage for the preparation of catalysts by heterogenisation of metal complexes. Four granular activated carbons and a carbon cloth showing different physical and chemical properties were used as sorbents. Adsorption of naphtoic acid was accomplished by all materials, being clear that an oxygen-rich surface chemistry has a negative effect on the physical adsorption of this molecule. The naphtoic acid molecule accommodates on the surface of narrow micropores. After adsorption, the samples were subjected to conditions similar to those used in hydrogenation reactions in order to quantify the amount of naphtoic acid that leaches from the surface of the adsorbent. According to the purpose of this research, all the carbons retain enough naphtoic acid. (C) 2004 Elsevier Ltd. All rights reserved.
