INTRODUCTION
of the multitude of industrial activities, surface treatment is one of the largest water consumers and polluters. The literature reports a multitude of processes for decontaminating polluted water from surface-treatment industries such as precipitation, extraction, evaporation, electrolysis, cementation, ion-exchange, adsorption onto activated carbons, ultrafiltration, and reverse osmosis. However, for technological and economic reasons, many of the processes proposed cannot be used on an industrial scale. Thus, there is a need to develop new treatments. In this sense, a new cyclodextrin-based material containing ionic groups for adsorption-oriented processes alone as well as in combination with oxidation has been developped.
