以粉煤灰为主要原料,添加超细电气石粉和烧结助剂,采用湿式超细研磨和低温煅烧工艺,制备粉煤灰基多孔陶瓷.利用扫描电镜、X射线衍射仪等对材料的结构和性能进行了表征.通过紫外-可见分光光度计,分析了粉煤灰基多孔陶瓷对孔雀石绿的脱色效果.结果表明:粉煤灰基多孔陶瓷孔径细小均匀,具有较强的吸附性;适量超细电气石粉的引入使粉煤灰基多孔陶瓷具有一定的降解能力,反应5h,孔雀石绿溶液脱色率达89.3%,结合傅立叶变换红外光谱,探讨了脱色前后孔雀石绿结构的变化,并进一步分析了孔雀石绿的脱色机理.

Fly ash-based porous ceramics was prepared by wet ultra-fine grinding and low-temperature calcining process using fly ash as main materials and ultra-fine tourmaline and binding agent as additive.The structure and properties of material were characterized by SEM,XRD,and decolorizing effect of fly ash-based porous ceramics to degrade malachite green (MG) was analyzed by ultraviolet-visible spectrophotometer.The results indicated that the materials had fine-uniform pore size and excellent adsorptivity.The addition of ultra-fine tourmaline proviede fly ash-based porous ceramics with degradation capacity,and the decolorizing rate of malachite green aqueous achieved to 89.3%.By means of FT-IR,the changes of the structure of malachite green were studied before and after decolorizing,and decolorizing mechanism of malachite green was also analyzed.
