| 摘 要： | 研究了粉煤灰 (FA)和浸渍粉煤灰 (IFA)吸附水溶液中有害的对硝基苯酚 ,试验了颗粒大小、浸渍条件、p H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 p H值 ,可增加粉煤灰对对硝基苯酚的吸附量 ;用 Al3+离子浸渍的粉煤灰具有较大的吸附量 ;吸附机理是多孔物质吸附和静电共同作用的过程。

| Abstract: | In the paper,the adsorption of toxic p nitrophenol by fly ash(FA) and impregnated fly ash(IFA) in aqueous solution have been investigated.The influences of various factors,such as particle size,IFA,pH and temperature on the adsorption capacity have been studied.The results show that the adsorption 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 adsorption capacity of FA for p nitrophenol.The mechanism of adsorption process is a correlative adsorption result between the porous substance and static function. |
