comparison of adsorptions of phenol,p-nitrophenol and 1-butanol on the activated carbon
نویسندگان
چکیده
adsorption of 1-butanol, phenol, and p-nitrophenol on activated carbon havebeen studied. the results were used to testifying the validity of different modelsbased on thermodynamic principles: freundlich, langmuir and henry isotherms.the maximum capacity of adsorbent for three compounds was determined, theconstants of equilibrium were determined by freundlich isotherm and virialisotherm expression for phenol and 1-butanol, respectively. the thermodynamicfunctions: ag',as',ah° , were calculated from the data of adsorption of phenol onactivated carbon as a function of temperature. in addition, adsorption of mixturesof phenol and p-nitrophenol under limited range of concentration were studied.finally arrangement of carbon atoms in activated carbon and surface coverage ofactivated carbon by phenol and 1-butanol for different configurations ofcompounds has been discussed.
