Adsorption of Organic Species by High Surface Area Styrene-Divinylbenzene Copolymers

Adsorptive Separation and Recovery of Chlorinated Phenols

“…For dichlorophenols, the adsorption equilibrium data could be satisfactorily fitted to Freundlich and Langmuir isotherms. The same behavior was also reported for 2,4-DCP on coconut coir (18) and also by Gustafson et al (19) on styrene-divinylbenzene copolymer.…”

Irreversible adsorption of phenolic compounds by activated carbons

“…These resins have high surface areas tusually 300-800 m2jg) because each particle is an agglomeration of microspheres with diameters as small as 1o-4 mm. The resins should interact with sorbed organics through dispersion forces, and binding energies should generally be lower than those for the same sorbates on an activated carbon (Gustafson et al, 1968). Under these conditions, adsorption should be completely reversible through solvent regeneration.…”

Design models for adsorption systems in wastewater treatment

“…The maximum flow rate, R (m3 of solution per m3 of adsorbent h-1) may be calculated from equations (17) and (18) with certain limitations as described by Johnston. (See reference49.)…”

“…normally results in minimum bed heights between 3 and 6 m. Bed heights>Zmin are desirable economically for longer on-stream lifetimes, but values of Z> 10 m should not be used because of difficulties in maintaining packing stability.Column diameters are limited to constructional details. For diameters c 1 m columns are usually made from pipes and for diameters 1-4 m (a maximum value for stable packing) plate fabrication is normally used.The maximum flow rate, R (m3 of solution per m3 of adsorbent h-1) may be calculated from equations(17) and(18)with certain limitations as described by Johnston.
