A study was made of the adsorption of 5-sulfosalicylic acid and orthophosphate ions from aqueous solutions by two commercially activated carbons. Adsorption isotherms obtenained at 298°K were both of Langmuir and Freundlich types and from them adsorption capacities were calculated. From these results, the activated carbon with a pH=8 adsorbs both adsorbates better than the other one (pH=7) and the orthophosphate ions are better adsorbed than the 5-sulfosalicylic acid. These results are comfirmed from theoretical calculations of accessible number of active sites obtained for both the activated carbons. It has also been shown that the percentage dispersion of these active sites is high at the surface. Those results correspond with the number of active sites accessible at the surface. L’adsorption de l’acide 5-sulfosalicylique et des ions orthophosphates en solution aqueuse par deux charbons actifs commerciaux a été effectuée. Les isothermes d’adsorption de Langmuir et de Freundlich ont été obtenues à 298°K et le calcul des capacités d’adsorption montre que les ions orthophosphates sont mieux adsorbés que l’acide 5-sulfosalicylique et que les deux charbons ont des propriétés d’adsorption liées au nombre de sites actifs accessibles, c’est-à-dire présents à la surface des grains.
