摘要/Abstract

摘要： 研究了Fe(Ⅲ)改性大孔磺酸型树脂对饮用水中氟离子的吸附特性.氟在载Fe(Ⅲ)树脂上的吸附不随pH的变化而变化，该吸附剂对氟的饱和吸附量随温度的升高而增加，吸附热力学方式符合Langmuir和Freundlich吸附等温式，吸附动力学符合Elovich和准二级动力学模型，而且代表性竞争离子对氟在树脂上的吸附无明显影响.在动态实验中，吸附剂展示了良好的动力学性能.结果表明载Fe(Ⅲ)树脂是一种很有前景的除氟吸附剂.

Abstract: Fluoride adsorption on Fe(Ⅲ) modified macroporous sulfonic acid resins has been investigated through batch experiments. The adsorption of fluoride on Fe(Ⅲ)-modified resins is independent of pH value，and the saturated adsorption capacity increase with the increase of temperature. The adsorption thermodynamics follows the Langmuir and Freundlich isotherm. The adsorption kinetic follows Elovich kinetic and the pseudo-second-order kinetic equation. The common foreign ions in drinking water do not obviously influence on the adsorption capacity of fluoride. The adsorbent shows good dynamic performance in column experiments. Results show that the Fe-modified resins would be a promising adsorbent for fluoride removal from drinking water.

Key words: fluoride ion, adsorption, Fe(Ⅲ)-modified resin, influence factor
