 abstract = {Monolithic PolyHIPE Polymer (PHP), being a highly porous, low density,
open cellular material was produced by polymerization of a high internal
phase emulsion (HIPE) in which the polymerizable continuous phase
consisted of monomers, styrene (STY), and divinyl benzene (DVB). The
inner dispersed phase (90 vol %) was an aqueous solution containing 0.4
wt % potassium persulphate as initiator. The resulting porous structure
had 12% crosslinking density. Surface chemistry of the monoliths was
modified by chloromethylation and amination to impart anionic
functionality. Surface modified monoliths had ion exchange capacity of
3.01 meq/g, and had the ability to uptake water about 10 times of its
mass. It was used Cr (VI) ion removal from aqueous solution. The
experimental results investigated for both the Langmuir and the
Dubinin-Radushkevich adsorption models. The maximum Cr (VI) adsorptions
are 126.6 mg Cr (VI)/g and 129.3 mg Cr (VI)/g, respectively. The mean
free energy E of adsorption is 11.18 kJ/mol according to the
Dubinin-Radushkevich adsorption model, indicating that the adsorption
occurs through a chemical ion-exchange process and it is not diffusion
limited. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015,
