Abstract: The adsorption process is being extensively used for the removal of dyes from synthetic dyehouse effluents by various researchers. The most widely used adsorbent is commercially available activated carbon. Despite the frequent use of adsorption in wastewater treatment systems, commercially available activated carbon remains an expensive material. In recent years, the safe and economical methods are required for the treatment of dyehouse effluents, which involved researchers to focus towards the preparation of low cost adsorbents from cheapest sources. Therefore, in this review article, the different cheapest sources of preparing adsorbent are discussed and their feasibility in treating dyehouse effluents is studied.
