摘    要:通过实验研究了沸石、膨胀蛭石、瓷砂陶粒、页岩陶粒和黏土陶粒5种硅酸盐吸附剂改性前后对腐殖酸的吸附的影响.分析了投加量、pH、温度和腐殖酸浓度对腐殖酸吸附的影响.结果表明:改性前,沸石对腐殖酸的吸附性最好,膨胀蛭石次之,黏土陶粒、瓷砂陶粒和页岩陶粒效果较差.改性后,5种硅酸盐吸附剂对腐植酸的吸附去除效果均有较好提高,其中5种硅酸盐吸附剂用HDTMA改性的最佳条件为:沸石、膨胀蛭石和黏土陶粒改性浓度均为20 g/L,页岩陶粒和瓷砂陶粒为25 g/L.

关 键 词:硅酸盐吸附剂  腐殖酸  改性  吸附  沸石

Abstract:This paper analyzes raw and modified silicate absorbents' absorbing capability for humic acid by doing experiments with zeolite,expanded vermiculite,porcelain ceramists,shale ceramists and clay ceramists.The effects of solution pH,the dosage of modified absorbents,temperature and initial humic acid concentration on adsorption capacity of humic acid were observed.The experimental results showed that there are significant differences between zeolite and other absorbents,and the adsorbing capacity in the order...
Keywords:silicate absorbent  humic acid  modification  adsorption  zeolite
