The industry surface treating uses numerous chemical products, in particular toxic metals and organic substances such as dyes, which are known to be harmful of humans and the environment.It is therefore necessary to remove these toxic pollutants from industrial waste for later disposal.The application of polymers in the fields of industry and agriculture has experienced an unprecedented development. Thus, they were used as finished products (plastics, paints, etc.) or as additives in the methods of processing and / or industrial processing (ion exchange resins, corrosion inhibitors, etc ...).

In recent decades, the modified polymers (hybrid organic-inorganic) have been applied in various fields, including adsorption of pollutants in waste water, for their efficiency applications. The intrinsic multifunctional character of these materials and there interesting properties makes them potentially useful in multiple fields including wastewater treatment.
