The capacity of adsorption of some natural changed or synthesized loam make the object in several applications to keep specific pollutants or in other techniques as in the manufacture of beauty products or medical. Tries are performed on water contaminated by known concentration of phenol. To characterize samples we undertook the techniques of diffraction in the ray X (DRX) to have information on the interleaf areas before and after adsorption and the thermograph (TG) to follow the loss of mass. The sample of bentonite pure is then analyzed by the microscopy with electronic scanning MEB-EDX to go taking up the specters of the various mineral elements and by the elementary chemical method using the fluorescence of X-rays.Analyses DRX and TG go up that there is a variation of interleaf distances and losses of masses, what confirms the presence of adsorbed phenol. Tries d ‘adsorption are accomplished with an initial concentration of phenol fixed to 5 mg by varying the mass of bentonite, phenol staying in resolution is determined to spectrophotometer UV in 270 nm. Adsorption Isotherms follow well the model of Langmuir and show a quantity q max = 75 mg of phenol substances kept by gram of bentonite. What confirms that purification by the adsorption can be accomplished or not according to the initial rate in phenol in water as well as an estimate of the mass of adsorbent who can reduce concentration of pollutants of an important manner.
