摘要：

The adsorption of benzoic acid and its derivatives to swollen chitosan beads increased with decreasing pK(a) value, except for those compounds having a hydroxyl group in the aromatic ring, The hydroxyl group had the ability to stimulate adsorption, this effect being stronger than that of pK(a)s. The presence of glucose and methanol also stimulated the adsorption of benzoic acid.
