The adsorption of normal and  -methylated series arenes on rhodium supported on two kinds of AlPO4 has been studied by using a gas-solid chromatographic technique. The adsorption process was exothermic ( Hads<0) and non spontaneous (Gads>0) the relative adsorption constants being fitted to the Pavelich-Taft equation in which the electrical effect of the alkyl substituent is the main influence.
