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．
In this paper, we studied the adsorption behavior of fulvic acid fulvic acid, which is widely used and fully characterized in our country, on 201 × 7 chloride strong basic anion exchange resin. The initial pH was 7.50 and 5.00, The initial concentration of fulvic acid is between 15 and 70 mg / l at 25 ° C, such as the mixing isotherm, the percentage of adsorption and the relationship between the reduction of fulvic acid concentration before and after adsorption and the chloride ion concentration released from the resin to the solution. The results show that the adsorption isotherms fit the Freundlich equation. In addition, the mechanism of adsorption of fulvic acid by strongly basic anion exchange resin was also discussed.
