A new pH method for determining surface acidity of ion exchange resin has been established.Results obtained from pH method can be compared with those obtained from UCT method. Re-sults also show a better correlation between the esterification catalytic activity of ion exchangeresin and the pH value measured by this new method. The pH method is a simple, quick and reli-able method for determining the surface acidity of ion exchange resin.
