Humic acids removal from water by aminopropyl functionalized rice husk ash.

Abstract

The use of rice husk ash (RHA) as an adsorbent for the adsorption of humic acids from water was studied. Optimum conditions for humic acids adsorption were found in batch method as follows, 60 min equilibrium time and initial in the range of pH 3-4. In addition, RHA was functionalized with 3-aminopropyltriethoxysilane. Again, the adsorption behavior of the… (More)
