吸附法是染料废水处理的重要方法，具有适应性广、操作简便和处理效果好等优点，但常用吸附剂存在成本高、吸附速率慢、吸附容量低及再生困难等缺点，迫切需要开发低成本、高效率和易再生的吸附材料。本申请在对吸附材料结构与性能关系深入分析的基础上，设计了一种新型的多级孔道结构功能性聚合物微球，用于染料分子的高效吸附。围绕这种设计，拟在以往研究工作基础上，开发出一种工艺简单、产率高、易于工业化生产的多级孔道结构聚合物中空粒子制备方法；并将所制备的多级孔道结构聚合物中空粒子进一步功能化，用于染料废水的处理；从热力学和动力学角度研究其对染料分子的吸附过程及机理，探究吸附性能和结构之间的构-效关系；从吸附选择性、吸附容量和吸附速率以及解吸附-再生等方面探讨其在染料废水处理领域的应用前景。本研究不仅在新型染料吸附材料结构设计方面具有重要学术价值，而且在染料废水问题的解决方面具有现实意义。

Adsorption process is one of the most effective techniques for dye removal due to its flexibility, simplicity and high efficiency. However, the disadvantages of conventional adsorbents, including relatively high cost, low adsorption capacity, slow adsorption rate and the difficulty in regeneration, remain big challenge for their industrial application. Therefore, the development of high performance, low cost and recyclable adsorbents has attracted considerable research attention. The adsorption performance of the adsorbents is largely dependent on their chemical composition and porous structure. Taking these into consideration, a novel kind of functional hollow polymer particle with crosslinked shell and multi-level porous structure are specially designed. The high surface-to-volume ratio, multi-level porous structure and high density of functional groups, making them suitable adsorbents for dyestuffs adsorption. Based on our previous work, we will develop a simple, high yield and scalable method for the fabrication of multi-level porous hollow polymer particles (MPHPPs). The as-prepared MPHPPs will be further functionalized and serve as an efficient adsorbent for the removal of dyestuffs, and the adsorption process and the adsorption mechanism will be fully studied. The selectivity of these functional MPHPPs to different kind of dyes, the adsorption capacity and rate, and their regeneration/reuse will be investigated in detail. The present research not only has great significance for the structure design of efficient adsorbent, but also leads to a series of high performance adsorbents for the treatment of dye wastewater.
