Abstract
Retention isotherms of 2,4-D in aqueous solution on an activated carbon at 10, 20, 30, 40 and 50ºC have been obtained. The activated carbon was prepared using almond shells as raw material. The retention process has been studied using the Langmuir, B.E.T. and López-González methods, wich were adapted to adsorption from solutions. The retention capacity of this carbon was around 10-3 mols.g-1. The surface area accesible to 2,4-D molecules as well as the thermodynarnic parameters of the process have been also calculated.
