Abstract

Highly selective gallic acid imprinted polymers were synthesized by a suspension polymerization technique Poly hydroxyethyl methacrylatecoethyleneglycol dimethacrylate and poly dimethoxystyrenecodivinylbenzene beads were studied for gallic acid separation from green tea leaves Isothermal binding was explained using Langmuir and Freundlich models Recovery of gallic acid molecules was significantly improved up to 83  when water was used as extraction solvent Competitive adsorption from a green tea leaves alcoholic extract revealed higher affinities of imprinted polymers for gallic acid An 188 selectivity coefficient was obtained for poly hydroxyethyl methacrylatecoethyleneglycol dimethacrylate imprinted beads The performances of the imprinted polymers were in agreement with morphology and nitrogen adsorption analysesThe work has been funded by the Sectorial Operational Program Human Resources Development 2007–2013 of the Romanian Ministry of Labour Family and Social Protection through the Financial Agreement POSDRU/88/15/S/60203 The authors also like to thank for the help and support of Dr Eng Florica Adriana Nicolescu
