摘要:
以硅藻土为主要原料,添加适量烧结助剂,采用干式研磨、滚球成型、高温煅烧工艺制备硅藻土基多孔陶粒。结合扫描电镜、能谱仪、压汞仪、白度仪等仪器对材料的结构与性能进行表征,通过紫外分光光度计考察材料对孔雀石绿的吸附降解。结果表明,硅藻土基多孔陶粒的孔径集中于100~5 000 nm,比表面积为6.28 m2/g,孔隙率为 56.96%,体密度、视密度分别为496.02、1 066.86 kg/m3,白度为84。硅藻土陶粒对甲基橙、直接桃红12B几乎没有吸附效果,对孔雀石绿吸附效果较好,陶粒量为20 g/L时3 h去除率可达65.92%。硅藻土陶粒与芬顿法联用,陶粒用量为1 g/L时,对孔雀石绿的去除率是单独使用硅藻土陶粒与芬顿法去除率之和的1.91倍;陶粒用量为13 g/L时,硅藻土陶粒超声催化对孔雀石绿的去除率是单独使用硅藻土陶粒与超声去除率之和的1.79倍。可见,硅藻土陶粒分别与芬顿法、超声法产生了明显的协同作用。
