Adsorption of Phenoxyacetic Herbicides from Water on Carbonaceous and Non-Carbonaceous Adsorbents

The increasing consumption of phenoxyacetic acid-derived herbicides is becoming a major public health and environmental concern, posing serious challenge to existing conventional water treatment systems. Among the various physicochemical biological purification processes, adsorption considered one most efficient popular techniques due its high removal efficiency, ease operation, cost effectiveness. This review article provides extensive literature information on by adsorbents. purpose this organize scattered currently used adsorbents for herbicide from water, such as activated carbons, carbon silica adsorbents, metal oxides, numerous natural industrial waste materials known low-cost capacity these was compared two herbicides, 2,4-dichlorophenoxyacetic acid (2,4-D) 2-methyl-4-chlorophenoxyacetic (MCPA). application kinetic models isotherms in describing also presented discussed. At beginning paper, important has been collected, including their classification, properties, occurrence environment.
