将羧基柱[5]芳烃与聚乙烯醇(PVA)通过酯化反应构筑了三维交联网络结构的吸附剂CP[5]-PVA。该材料对刚果红(CR)染料和中性红(NR)染料具有快速高效的吸附效果：对CR染料的吸附效率在30 min内达到96.85%，对NR染料的吸附效率在45 min内达到99.92%。CP[5]-PVA对CR和NR的吸附过程符合准二级动力学模型和Langmuir等温吸附模型，最大吸附量分别为258.40 mg/g和125.16 mg/g。
Abstract：The adsorbent of CP[5]-PVA was prepared by esterification of carboxyl pillar[5]arene and polyvinyl alcohol. It has a fast and efficient adsorption effect on congo red(CR) dye and neutral red(NR) dye, respectively. The adsorption efficiency of CR reached 96.85% in 30 min, and the adsorption efficiency of NR reached 99.92% in 45 min. The adsorption process of CP[5]-PVA on CR and NR dyes conformed to the quasi-second-order adsorption kinetic model and the Langmuir isothermal adsorption model, and the maximum adsorption capacity was 258.40 mg/g for CR and 125.16 mg/g for NR, respectively.
