“…For example Caturla et al (1988) have reported that when narrow micropores dominate in the porous texture, the adsorption of phenolic compound correlates with the BET surface area while for carbon with predominant contribution of wider pores, the surface properties influence the adsorption of phenol as well. Daifullah and Girgis (1998) reported that the main factor that determines phenolic compounds adsorption is the pore size distribution (PSD) of adsorbent.…”

The adsorption of phenol on microporous activated carbons (ACs) produced in laboratory from polyethyleneterephtalate (PET), furfuryl alcohol (PFA), polyacrylonitrile (PAN) and anthracene oil pitch (ASN) have been studied. The ACs have been obtained by carbonization and subsequent steam activation at 850°C to 50 % burn off. For comparison, commercial activated carbons from coconut shell, and CWZ 22 carbon have been applied. All studied ACs are predominantly microporous and have neutral or basic surface characteristics. The pseudo second kinetic model and Langmuir equation were found to fit the experimental data very well. A very good correlation between the volume of pores with a width smaller than 1.4 nm (V 1.4 ) and the volume of phenol calculated from Langmuir monolayer capacity (q m ) was found. Based on that, it can be concluded that the phenol adsorption is governed mainly by micropore filling through the p-p dispersion interaction in micropores smaller than double molecular diameter of phenol.

“…For adsorbate and solvent the adsorption phenomenon depends on the differences between their chemical properties, structure and interactions (mutual and with solid surface). The adsorption of various series of different organic adsorbates was analyzed to find some correlations between the sorption experimental data and the properties of adsorbate and adsorbent [4,[10][11][12][13][14][15][16][17][18][19]. Many of benzene derivatives possess acidic or basic functional groups.…”

Adsorption of benzene derivatives of various chemical properties from dilute aqueous solutions on the Norit activated carbons is investigated. The experimental systems are analyzed in terms of adsorption theory on energetically heterogeneous solids. The relations between the optimization isotherm parameters, i.e. equilibrium constants and heterogeneity parameters, and the solute properties, e.g. number, character and position of functional groups are discussed. #

The adsorption of o-, m-and p-nitrophenols on clinoptilolite type natural zeolite has been studied as a function of the solution concentration and temperature. The adsorption rates were observed to be equal to the first-order kinetics. The rate constants were calculated for 25.0 -40.0 -50.0°C at constant concentration. The activation energies, (E a ) for nitrophenoles adsorption on zeolite, were estimated using the Arrhenius equation. Thermodynamic parameters were calculated for all nitrophenols. Adsorption isotherms of o-, m-and p-nitrophenols on natural zeolite were determined. These isotherms were modeled according to the Freundlich and Langmuir adsorption isotherms. The isotherms for nitrophenols on clinoptilolite were assigned as L curves. The L curve of p-nitrophenol is two step while the L curves of o-and m-nitrophenols are one-step.
