摘　　要：本文研究了微波作用下硅藻土中Ａｌ＿２Ｏ＿３，Ｆｅ＿２Ｏ＿３析出量与硫酸浓度、固液比、作用时间的关系．找出了将二、三级品位的硅藻土提纯为一级硅藻土的途径。探讨了微波加快化学反应速率的机理。Microwave could quicken the rate of chemical reaction, his artical gives the rela- tion between the separate quantity of Fe_2O_3, Al_2O_3 and the concentration of H_2SO_4,affectedtime,solid-liquid ratio in diatomic which was affected by microwave,thus we have found theway to purify the diatomic from the second or the third grade to the first grade. In the otherhand,this artical discusses the mechnism that microwave quickens the rate of chemical reac-tion.
