【摘要】 本文用静态法研究了我国广泛应用及充分表征的巩县风化煤富里酸在氯式强碱性阴离子交换树脂２０１×７上的吸附行为，测定了起始ｐＨ为７．５０及５．００，富里酸起始浓度介于１５至７０ｍｇ／ｌ条件下，２５℃时的吸附等混线、吸附百分数以及吸附前后富里酸浓度的减少与从树脂释放到溶液中的氯离子浓度的关系．结果表明，吸附等温线符合Ｆｒｅｕｎｄｌｉｃｈ型方程．此外，还讨论了强碱性阴离子交换树脂吸附富里酸的机理．更多还原

【Abstract】 The sorption characteristics of the fulvic acid from weathered coal on 201×7 stronglybasic anion exchange resin in Cl- form were studied using the batch method. The sorption isotherms at PH 5 and 7.5 were determined and it was found that the isotherms obey the Freundlich equation over a concentration region of the fulvic acid from 15 to 70mg/l. the dependence of sorbed amount of the fulvic acid on the Cl- concentration released from 201×7 resin in the solution was obtained, and the mechanisms of sorption of the fulvic acid on strongly basic anion exchaange resin was discussed.更多还原
