| 20100326921 | Process for obtaining an adsorbent from a waste material and use of the adsorbent - In the present, a procedure of obtaining adsorbent from a waste material and its use are disclosed. This invention provides a natural waste material, specifically avocado seed, its preparation and use for the filling of columns used in the elimination of contaminants present in wastewater. The particles have an irregular shape and variable size for filling columns of different diameter and length. The adsorbent has the sufficient hardness for avoiding a particle collapse. The material does not rot, is re-generable and ecological.
