Abstract

Eleven of the sixteen polycyclic aromatic hydrocarbons (PAH) which appear on the US Environmental Protection Agency priority pollutant list have been investigated with respect to adsorption onto activated carbon. Adsorption characteristics were examined in terms of PAH molecular and physicochemical properties. The partitioning behavior of PAH was investigated by generating adsorption isotherm data for eleven PAH from water onto Filtrasorb 400 activated carbon at 25/sup 0/C using batch shake testing. An evaluation of the Henry's Law, Langmuir, BET, Freundlich and Redlich-Peterson adsorption isotherm equations indicated that the Langmuir equation most appropriately represents the data. Fitting the data to two linearized forms of the Langmuir equation provides estimates of the Langmuir parameters b and q/sup 0/ which apply over different equilibrium concentration (c/sub e/) ranges. The products of the parameters bq/sup 0/ obtained using the low c/sub e/ linear form of the Langmuir equation approximate Henry's Law adsorption constants. These values range from 2390 mg/g per mg/l for naphthalene to 326,000 mg/g per mg/l for chrysene. The parameter q/sup 0/ obtained using the high c/sub e/ linear form of the Langmuir equation reflects limiting adsorption capacity. These values range from 580 mg/g for naphthalene to 14.7 mg/g for benz(a)anthracene. The highmore »« less

Equilibrium adsorption of polycyclic aromatic hydrocarbons from water onto activated carbon

Journal Article Walters, R; Luthy, R - Environ. Sci. Technol.; (United States)

Adsorption isotherm data for 11 polycyclic aromatic hydrocarbons (PAH) from water onto Filtrasorb 400 activated carbon at 25/sup 0/C have been generated by batch shake testing. An evaluation of Henry's law, Langmuir, BET, Freundlich, and Redlich-Peterson equations indicates that the Langmuir equation is most useful for representing the data. Fitting the data to two linearized forms of the Langmuir equation provides estimates of the capacity term q/sup 0/ and the energy term b which apply over different equilibrium concentration (C/sub e/) ranges.

Adsorption studies evaluating codisposal of coal gasification ash with wastewater sludges containing polycyclic aromatic hydrocarbons

Technical Report Kilmer, J; Minear, R; Francis, C

The extent to which polycyclic aromatic hydrocarbons (PAHs) are sorbed onto gasifier ash was investigated in batch and column sorption studies. The batch studies involved characterizing the adsorption and desorption of phenanthrene, anthracene, benzo(a)pyrene, and quinoline on gasifier ashes from four coal gasification processes. The surface area of ashes ranged from <1 to >30 m/sup 2//g. Isotherms representative of adsorption and desorption over wide ranges in equilibrium concentrations of the PAHs were determined. Five sorption models, Freundlich, Langmuir, Henry's Law, BET (Brunauer, Emmett, and Teller), and Redlick-Peterson were examined to determine which model best described the adsorption/desorption characteristics of themore »« less
Mass transfer kinetics of adsorption on suspended solid particles

Journal Article Ditl, P; Coughlin, R; Jere, E - J. Colloid Interface Sci.; (United States)

A kinetic model was designed for adsorption from liquid to spherical particles with consideration of effects of adsorbate concentration changes in the liquid on mass transfer, as it occurs in agitated batch adsorption. The mass transfer was formulated for Langmuir, Freundlich, and linear isotherms and solved numerically. Application of the theoretical results to adsorption of dextrose (Langmuir isotherms) and urea (linear isotherms) on carbon from dilute aqueous solutions under conditions resembling those of wastewater treatment gave results in good agreement with experimental adsorption results obtained at 0/sup 0/, 26/sup 0/, and 49/sup 0/C with untreated or oxidized Calgon Filtrasorb 300more »« less

Journal Article Nakhjiri, Mahdi; Kurdtabar, Mehran - Journal of Polymers and the Environment

In this study, the collagen-g-poly(acrylic acid-co-N-vinylpyrrolidone)/Fe{sub 3}O{sub 4}@SiO{sub 2} (collagen-g-p(AA-co-NVP)/Fe{sub 3}O{sub 4}@SiO{sub 2}) as magnetic nanocomposite hydrogel was synthesized by graft copolymerization of acrylic acid (AA) and N-vinylpyrrolidone (NVP) onto collagen in the presence of the Fe{sub 3}O{sub 4}@SiO{sub 2} using ammonium persulfate as a free radical initiator and bis[2-(methacryloyloxy)ethyl] phosphate as a crosslinker under ultrasound-assisted condition. The blank collagen-g-p(AA-co-NVP) hydrogel and its composite with the Fe{sub 3}O{sub 4}@SiO{sub 2} nanoparticles were characterized by means of FTIR, SEM-EDS, XRD, VSM and TGA methods.
