Summary: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. In the present invention the preparation of the adsorbent, its pre-activation, carbonization and application to eliminate the color of textile wastewater is disclosed. The color elimination from textile wastewater, as well as decrease of salts, total suspended solids, chemical oxygen demand (COD) and total organic carbon (TOC), is carried out passing the textile wastewater through a column filled with the prepared adsorbent. In batch systems metals dissolved in water can be eliminated. En el presente, se da a conocer un procedimiento de obtención de adsorbente a partir de un material de desecho y su uso. Esta invención provee de un material natural de desecho, específicamente de la semilla del aguacate, su preparación y su uso para relleno de columnas empleadas en la eliminación de contaminantes presentes en agua residual. Las partículas tienen forma irregular y un tamaño variable para rellenar columnas de diferente diámetro y longi.tud. El adsorbente tiene la dureza suficiente para evitar que las partículas se colapsen. El material no se pudre, es regenerable y ecológico. En la presente invención se describe la preparación del adsorbente, su pre-activación, carbonización y aplicación para la eliminación del color en agua residual textil. La eliminación del color de agua residual textil, así como la disminución del contenido de sales, de sólidos totales suspendidos, de la demanda química de oxígeno (DQO) y del carbono orgánico total (TOC), se realiza haciendo pasar el agua residual textil por una columna de rellena con el adsorbente preparado. En sistema batch pueden eliminarse metales disueltos en agua.
