中文摘要：

采用竹屑、骨粉及膨润土三者混合,经炭化活化制得炭陶除氟吸附材料。研究原料配比、升温速率、活化温度和保温时间等对除氟吸附材料平衡吸附容量及除氟率的影响,并采用扫描电子显微镜（SEM）及傅里叶转换红外光谱仪（FTIR）对炭陶样品进行表征。结果表明：随着升温速率、活化温度及保温时间的增加,炭陶除氟吸附材料的平衡吸附容量及除氟率均呈现先增加后降低的趋势;同时,炭陶除氟吸附材料在除氟过程中,既有物理吸附又有化学吸附,这种协同效应大大提高了其除氟性能。在相对较优的试验条件下,炭陶除氟吸附材料的平衡吸附容量为2.214 mg.g-1,除氟率为88.56%。

英文摘要：

The carbon/pottery composite for removing fluoride is prepared from bone dust,bamboo power,clay by carbonization and activation process.Research on the effect of material proportion,heating rate,activation temperature and holding time for defluoridation capacity and the efficiency of defluoridation of carbon/pottery adsorption composite,and the characteristics of carbon/pottery composite have been studied by SEM and FTIR.It is found that,with heating rate,activation temperature and holding time increasing,defluoridation capacity and the efficiency of defluoridation of carbon/pottery adsorption composite tend to increase at first and then reduce.Meanwhile,physical adsorption and chemical adsorption occur when the carbon/pottery composite is used for removing fluoride.Therefore,a kind of synergistic effect appears,which improves the effect of carbon/pottery composite for removing fluoride.Under the optimized conditions,the defluoridation capacity of carbon/pottery adsorption composite is 2.214 mg·g-1,and the efficiency of defluoridation is 88.56%.
