Adsorption is a common method to treat organic dye pollution in industrial wastewater. Selective adsorption and reuse can greatly reduce the waste of adsorbents. Among the adsorbents of many different materials, the porous polymer microspheres as adsorbents have the characteristics of good adsorption effect, wide application range and large modification space, showing the unique advantages different from the traditional carbon materials. As a new kind of porous polymer material, polyionic liquid porous microspheres have great potential in the field of organic dye adsorption. In this paper, the selective adsorption of anionic organic dyes by a novel monodisperse pyridine polyionic liquid microsphere as an organic dye adsorbent was studied and the adsorption mechanism was studied.

吸附是处理工业废水中有机染料污染的常用方法。选择性吸附再利用可大大减少吸附剂的浪费。在众多不同材料的吸附剂中，作为吸附剂的多孔聚合物微球具有吸附效果好、应用范围广、改性空间大等特点，显示出不同于传统碳材料的独特优势。作为一种新型多孔高分子材料，聚离子液体多孔微球在有机染料吸附领域具有巨大的潜力。本文研究了一种新型单分散吡啶聚离子液体微球作为有机染料吸附剂对阴离子有机染料的选择性吸附，并研究了吸附机理。
