| Abstract: | The structure of attapulgite and the mechanism of its modification have been studied by specific surface area, scanning electromicroscopic analysis, differential thermal analysis, and X-ray spectroscopic analysis. The result showed that tempered attapulgite was better than treated with acid or salt. Treatment of dyeing waste water could be carried out satisfactorily with adsorbents based on temperature at 420C for 2 hours attapulgite, removal rate of 75% and 97% could be achieved for COD and color respectively. The study provided valuable experimental data for modifying attapulgite and applying to treating dyeing wastewater. |
