Abstract

See full text

Toxic or otherwise contaminating organic impurity constituents in aqueous media such as waste water streams from industrial processes or potable water supplies are removed and converted to harmless oxidation products by contacting such media with an organophilic molecular sieve whereby the organic species are concentrated as adsorbates, and thereafter contacting the adsorbate-loaded molecular sieve with an aqueous solution of a compound which has a standard oxidation potential of at least 0.25 volt in an amount and for a sufficient time to convert the organic materials to non-toxic products such as CO.sub.2.
