Journal ArticleDOI
TL;DR: The technical feasibility of the use of activated carbon, synthetic resins, and various low-cost natural adsorbents for the removal of phenol and its derivatives from contaminated water has been reviewed and it should be noted that the adsorption capacities of the adsorbent vary significantly depending on the characteristics of the individual adsorbENT, the extent of chemical modifications, and the concentrations of solutes.
