But today it is seen that the ground and water pollution, accidentally or voluntarily. Various industries, such as textile, are widely ejected a large volume of colored aqueous effluents. Their presence in water has more or less serious incidences to aquatic life and also it severe damages to the human bodies. Various technologies have been developed for decontamination Adsorption process has been proven as one of the best wastewater treatment technologies around the world. Research is centered on the use of new low cost materials, available locally, biodegradable, manufactured from natural sources. Because of their very significant structure, their great specific surface and their great capacity of adsorption, the adsorbents from clays were largely used to treat various effluents. In the present study, detailed experiments are carried out to remove brilliant green and methylene blue by adsorption technique using bentonite as an adsorbent. Based on the results obtained from the study, it appears that the acid activated clays constitute a good adsorbent for removing cationic dye.enPollutionwaterdyeclaybentoniteadsorption.Intervention
