摘要

In this paper, Cr~(3+) -modified bentonite was prepared and the adsorption of phenol, 1,4-dihydroxybenzene and aniline that can form hydrogen bonds with water molecules by the Cr-bentonite were studied. The optimal conditions, sample mass, stability and regeneration in the course of adsorption were investigated in detail. COD from garbage leachate as a comprehensive index of organic contaminants was used to examine the experimental effects, and a simple economic comparison with other conventional adsorbents was made. Possible mechanism was discussed.
