|Title:||Adsorption characteristics of chloramine-T on activated carbon|
|Abstract:||The adsorption behaviour of chloramine-T (CAT) from aqueous solutions on activated carbon is studied at 298,303,3 10 and 315.5K. The obedience to Langmuir (LAI) and Freundlich(FAI) adsorption isotherms is good while the obedience to Harkins Jura (HJAI) and Temkin(TAI) adsorption isotherms is poor. The specific adsorption is found to decrease with increase in temperature. From kinetic studies kinetic parameters such as rate constant at each of the above temperatures, energy of activation for the adsorption process, half life period and Elovich constants have been evaluated. Calorimetric enthalpy of adsorption is determined and other enthalpies of adsorption have been evaluated. The specific surface area of AC determined by BET method is lower than that determined by Langmuir method. A probable mechanism of adsorption is suggested.|
