Nhiệt hấp thụ của P-Nitrophenol, P-Nitroanilin và 2,4 - Dinitrophenol trên than hoạt tính

The heat of adsorption was determined from isotherm parameters, which in turn were calculated by Frendlich equation. The method was applied for the determination of adsorption heat of p-nitrophenol, p-nitroaniline and 2,4-dinitrophenol on TW-2 and CAL 12× 40 activated carbons. With the approach, it is easily to cover the influence of the whole range of surface loading on the heat of adsorption, especialy in low surface coverage.
