Journal ArticleDOI
Modeling of adsorption isotherms of phenol and chlorophenols onto granular activated carbon. Part I. Two-parameter models and equations allowing determination of thermodynamic parameters.
TL;DR: Adsorption isotherms modeling shows that the interaction of phenolic compounds with activated carbon surface is localized monolayer adsorption, which correlates well with respective increase in molecular weight, cross-sectional area, and hydrophobicity and decrease in solubility and pKa.
Journal ArticleDOI
Batch study of liquid-phase adsorption of methylene blue using cedar sawdust and crushed brick
TL;DR: Cedar sawdust and crushed brick can be attractive options for dye removal from dilute industrial effluents and are indicated to be effective adsorption mechanisms.
Journal ArticleDOI
Modeling of adsorption isotherms of phenol and chlorophenols onto granular activated carbon. Part II. Models with more than two parameters.
TL;DR: The adsorption equilibrium isotherms of five phenolic compounds from aqueous solutions onto granular activated carbon were studied and modeled in this paper, and the experimental data were analyzed using thirteen models with more than two-parameter; nine threeparameter equations -the Redlich-Peterson, Sips, Langmuir-Freundlich, Fritz-Schlunder, Radke-Prasnitz (three models), Toth, and Jossens isotherm -and one fiveparameter equation -the Fritz-schlunder isother
Journal ArticleDOI
Sonochemical degradation of Rhodamine B in aqueous phase: effects of additives.
TL;DR: In this paper, the effects of various additives such as iron (elemental, bivalent and trivalent), carbon tetrachloride, hydrogen peroxide, tert-btyl alcohol, salt (Na2SO4), sucrose and glucose on the sonochemical destruction of Rhodamine B (RhB) in aqueous phase were studied.
Journal ArticleDOI
Batch sorption dynamics and equilibrium for the removal of cadmium ions from aqueous phase using wheat bran.
TL;DR: Thermodynamic parameters indicate that the sorption of cadmium by wheat bran is a spontaneous process and physical in nature involving weak forces of attraction and is also endothermic.
