Abstract. The lignocellulosic residues can be developed in the treatment of wastewaters as clean and low costs natural adsorbents. In the present study, our approach consists to develop the preparation and physico-chemical characterization methods of an adsorbing material, starting from the barks of eucalyptus “eucalyptus camaldulensis”. The preparation of the adsorbent material comprises the sieving of barking, extraction of extractable, treatment with formaldehyde as activating agent, and chemical treatment with acrylic acid by the grafting reaction. The chemical modification is checked using means of analysis such as: Fourier transform infrared (FTIR), X-rays Diffraction (DRX) (Index of crystallinity) and method of Boehm. The chemical modification of the lignocellulosic material induced by a change in the microstructure of the material, especially in the case of grafting of acrylic acid and the crosslinking with formaldehyde in favor of the rise in the potential of adsorption capacity .
