Abstract
In the process for removing organic impurity constituents from aqueous media by adsorbing same on an organophilic molecular sieve adsorbent, followed by regeneration of the adsorbent by contact with an oxidant, such as hydrogen peroxide, whereby the organic adsorbate is converted to innocuous materials, principally CO.sub.2 and H.sub.2 O, the efficiency of the regeneration operation is found to be substantially improved by decreasing the pH of the regenerating medium and/or increasing the number of Bronsted acid sites in the molecular sieve adsorbent.
