| Abstract: | Influence of insolubilized humic acid on adsorption of hexavalent chromium in the sand matrix was investigated.Effects of reaction time,pH,concentrations of IHA and adding amount etc.on the adsorption of Cr(Ⅵ) were examined while the optimum reaction conditions were determined.Study indicated that the maximum removal rate of chromium by insolubilized humic acid was up to 98% in aqueous solutions with the reaction time of 6h at pH7.The kinetic curves and the adsorption isotherm curves of chromium affected by insolubilized humic acid were drawn. |
| Keywords: | Insolubilized Humic Acid Hexavalent Chromium Sand Adsorption |
