Abstract
In this work, adsorptive removal and photocatalytic degradation of Acridine Orange (AO), dye, and DNA indicator has been investigated in aqueous solution using natural clay as adsorbent and photocatalyst in batch mode. The total degradation of AO was tested via UV-vis spectrophotometer and chemical oxygen demand methods. As well, the investigated material was tested in the degradation of a real effluent collected from a Tunisian textile company. Obtained results confirm the high photocatalytic activity of the purified clay for AO mineralization and its great performance in the purification of real wastewater contains organic pollutants. Since the physicochemical characteristic of treated effluent conforms to the norms for reuse in agriculture (NT 106.3 (1989)), this recycling water can be used in irrigation vegetation.
