Effects of temperature and inorganic salts on the adsorption of phenol from multicomponent systems onto a decolorizing carbon
- Jordan Univ. of Science and Technology, Irbid (Jordan)
Experimental investigation of the effect of temperature and two inorganic salts (KCl and NaCl) on the adsorption of phenol from dilute (10-200 mg/dm{sup 3}) multi-component systems onto activated carbon was studied. Focusing on the adsorption of phenol, all combinations of phenol with two other aromatic organic components, (1,4-dihydroxybenzene and 4-amino,1-naphthalene sulfonic acid-sodium salt) in aqueous solutions were considered. Equilibrium isotherms at three different temperatures (30, 40, and 55{degrees}C) were generated. The adsorption of phenol from binary and ternary as well as from single aqueous systems increases with decreasing temperature, as expected of physical adsorption. Effects of KCl and NaCl salts as a concentration of 0.05 M at 30{degrees}C were also investigated. The adsorption of phenol from bisolute and trisolute systems slightly decreases by adding either of the salts.
