Adsorption of Polar and Non-polar Vapours by Activated Carbons. Adsorption Isotherms, Thermodynamics and Kinetics

      Аннотация: Adsorption of organic vapours has been the subject matter of numerous investigations during the last several decades in view of their toxicity and adverse effect on human health and environment. Activated carbons, because of their high surface area, high degree of surface reactivity and extensive microporosity have been considered as preferred adsorbents for the removal of these vapours. The book describes the adsorptive removal of polar and non-polar organic vapours using activated carbons of different origin before and after modification with different techniques. The influence of porous and chemical structures of the carbon surface as well as the molecular dimensions and polarity of adsorbate molecules on the adsorption of toxic organic vapours has been studied. Further, the interactions of these polar and non-polar compounds with activated carbon surface have been discussed on the basis of adsorption isotherms, thermodynamics and kinetics data. The book will help the readers in understanding the parameters and mechanisms involved in adsorption of organic vapours and to promote the research towards the development of novel activated carbons with modified surface chemistry.
