摘要：

Aromatic acidic compounds have been separated by ion exclusion chromatography. The theoretical equation, which relates the retention volume of an eluted acid to its dissociation constant, failed for aromatics, which show higher retention volumes than predicted. An important role is played by hydrophobic adsorption, which can be increased by addition of ion interaction reagents to the mobile phase.
