摘　　要：以电厂的废弃物粉煤灰为原料 ,研究了 12 73K温度下 ,粉煤灰和添加剂粉末制得了孔隙率较高的多孔玻璃微珠的过程。并对其吸附性能做了初步研究。用氮吸附静态容量法 ,测得该多孔玻璃微珠的氮吸附等温线、比表面和孔分布曲线。探讨了多孔玻璃微珠吸附特性和成珠条件。The study that porous glass beads with high adsorpti on were synthesized by self transformation of fly ash and additive,with the temp erature range of 1273K.The procedures include grinding,phase separation,acid t reatment.and its adsorption feature was investigated.The adsorption properties o f the porous glass beads were characterized by adsorption isotherm,specific sur face and pore distribution with the help of N 2 adsorption,and conclusions on adsorption characteristics and bead condition are presented.
