摘要
研究了水溶液中粉煤灰 (FA)和浸渍粉煤灰 (IFA)吸附有害的邻甲酚 ,试验了颗粒大小、浸渍条件、pH值和温度等因素对吸附量的影响。结果表明 ,在稀溶液中进行吸附时 ,提高温度、减小粒径和 pH值 ,可增加粉煤灰对邻甲酚的吸附量 ;用Al3+ 离子浸渍的粉煤灰具有较大的吸附量 ;吸附过程机理主要是多孔物质和静电作用的共同结果所致。
In the present study,the sorption of toxic o cresol by fly ash(FA) and impregnated fly ash(IFA)in aqueous solution has been investigated.The influences of various factors,such as particle size,IFA,pH and temperature on the sorption capacity have been studied.The results show that the sorption capacity of coal fly ash impregnated with Al 3+ ion is higher than Fe 3+ ion ,increasing temperature and decreasing particle size and pH increased the sorption capacity of FA for o cresol ,the mechanism of adsorption process is a correlative sorption result between the porous substance and static function.
