Phenol and its derivative compounds have received considerable attention from environmentalists, due to their undesirable effects in the water environment, where they end up as a result of improper disposal methods. As a result, concern about environmental protection has increased over the years from a global viewpoint. So research has been conducted all around with the common goal of reducing their concentrations to allowable limits or converting them to non-toxic, non-hazardous forms that may be released easily into the environment. Adsorption process has been proven one of the best water treatment technologies and activated carbon is undoubtedly considered as effective adsorbent for the removal of phenol from water. However, widespread use of commercial activated carbon is sometimes restricted due to its higher costs. Investigations have been made to develop inexpensive adsorbents utilizing numerous agricultural waste materials. By using these waste materials as locally available adsorbents is attractive due to their contribution in the reduction of costs for waste disposal, therefore contributing to environmental protection. In this review, the technical feasibility of locally available adsorbents prepared by utilizing different types of waste materials from literature has been compiled and their adsorption capacities for phenol removal as available in the literature are presented.
