Preparation of Pyridine Polyionic Liquid Porous Microspheres and Their Application in Organic Dye Adsorption

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.
