Adsorption behaviour of N-haloarene sulphonamidates on activated carbon at303 K

By batch studies adsorption behaviour of some sodium-N-haloarene sulphonami dates (NHAS) such as chloramine-B (CAB) and bromamine-B (BAB), chloramine - T (CAT) and its bromo analogue (BAT) on activated carbon (AC) is studied a t 303 K. Langmuir adsorption isotherm (LAI), Freundlich adsorption isotherm (FAI) and Temkin adsorption isotherm (TAI) are well obeyed while Harkins J ura adsorption isotherm (HJAI) is poorly obeyed. The constants of these ads orption 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 adsorbate s is almost the same. The dimensions of the adsorbates have been calculated .
