Open publisher page 1 citations

Abstract

Adsorption and desorption experiments were carried out to screen the suitable macroporous absorbent resin for pomegranate peel polyphenols.Results indicate that macroporous resin HZ-818 possesse the strongest absorbend ability and easier desorption property.The optimum absorption conditions of macroporous resin HZ-818 are concentration of feeding 2.5 mg/mL,pH 3.0,feeding rate 5 BV/h.And the optimum desorption conditions are eluteethanol concentration 70 %,elution rate 2 BV/h,with the polyphenols mass fraction increasing from 34.0 % to 72.3 %.
