Extraction properties of new polymeric sorbents in SPE/GC analysis of phenol and hydroquinone from water samples

The influence of the polymers’ properties on the solid-phase extraction recovery was studied. Different porous copolymers were used: di(methacryloyloxymethyl)naphtalene–divinylbenzene with ester functional groups (DMN–DVB), 4,4′-bis(maleimido)diphenylmethane–divinylbenzene with imide functional groups (BM–DVB), p,p′-dihydroxydiphenylmethane diglycidyl methacrylic ester–divinylbenzene (MEMDE–DVB) and p,p′-dihydroxydiphenylpropane diglycidyl methacrylic ester–divinylbenzene (MEDDE–DVB) with ester end hydroxyl functional groups. The extraction properties of new synthesized polymeric sorbents were compared with these of two commercial polymeric sorbents: styrene–divinylbenzene (SDB-1) and styrene–divinylbenzene with modified surface (StrataX). These sorbents were used in the SPE of phenol and hydroquinone from water samples.
