| Abstract (English): |
A new type of ch让osan・cellulose・aJttapulgite composite aerogel material was prepared, which has an ideal removal effect on copper containing wastewater, under the optimal condition, the removal ratio can reach up to 85% ・ The adsorbed copper ions were immobilized on the aerogel materials to obtain copper loaded attapulgite based composite catalytic materials, realizing the recycling and sequential utilization of materials. The catalytic material has an ideal effect on treating methylene blue, with a removal ratio of 99・ 6% under the optimal conditions, in addition, this material still maintains a high treatment capacity in the treatment of compound wastewater・ The aerogel materials before and after adsorption were tested and analyzed by SEM, FTIR, XRD and TG・ The results showed that the materials had stable properties, high porosity, and copper could be uniformly loaded on the aerogel materials after immobilization・ This study can provide new ideas for the treatment of composite polluted wastewater containing heavy metals and recalcitrant organic compounds・ [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
备了新型壳聚糖-纤维素-凹凸棒石复合气凝胶材料, 对含铜废水去除效果理想, 最优条件下去除率可高 达85%。将吸附的铜离子固定在气凝胶材料上得到铜负载的凹凸棒石基复合催化材料, 实现材料的循环利用及循 序利用。该催化材料处理亚甲基蓝效果理想, 在最优条件下去除率高达99.6%, 此外该材料在混合废水的处理中 仍然保持较高处理能力。对吸附前后的气凝胶材料进行电镜扫描、傅里叶红外、X射线衍射和热重等测试分析, 结 果表明材料性质稳定, 孔隙率高, 吸附焙烧后铜可均匀负载在气凝胶材料上。该研究可为重金属和难降解有机物 复合型污染废水的处理提供新思路。 [ABSTRACT FROM AUTHOR] |
