| Abstract: | 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. |
| Keywords: | fly ash porous glass beads phase separation adsorpt ion isotherm |
