There is a serious environmental concern being encountered for increase in the rate of water pollution occurs by the contamination of several industrial discharges. The key issue of the contamination water is owing to the content of various non degradable toxic components in it which lead to cause life threatening to both plants and animal lives. In particular, the industrial effluent bears substantial amount of waste dyes, pesticides and pharmaceuticals wastes and those are carcinogenic in nature. This review is an attempt to cover the adoption of various activated sorbents including, charcoal, activated carbon, clay materials, organic extracts of the plants and nanomaterials for sorption studies of waste contaminates from the different kinds of waste water. The origin of organic pollutants, their nature, development of numerous activated adsorbents, characteristics properties of the sorbents and their suitable adoption for removal of contaminates is systematically discussed. The significance of the sorption mechanism accomplishing the kinetics, isotherm and thermodynamics on interaction of the adsorbents with organic pollutants are extensively described and reported.
