Abstract: By batch studies adsorption behaviour of some sodium-N-haloarene sulphonamidates (NHAS) such as chloramine-B (CAB) and bromamine-B (BAB), chloramine- T (CAT) and its bromo analogue (BAT) on activated carbon (AC) is studied at 303 K. Langmuir adsorption isotherm (LAI), Freundlich adsorption isotherm (FAI) and Temkin adsorption isotherm (TAI) are well obeyed while Harkins Jura adsorption isotherm (HJAI) is poorly obeyed. The constants of these adsorption isotherms have been evaluated and their variation with adsorbate is analysed. The sorption capacity for different NHAS has been arrived and it is more for CAT than for CAB. Similarly it is more for BAT as compared to that of BAB. The specific surface area determined with these four adsorbates is almost the same. The dimensions of the adsorbates have been calculated.
