摘要：
A compressible ZIF-67/polyacrylamide/chitosan composite aerogel (named as ZIF-67/PAM/CSA) is prepared by two-step method with in-situ polymerization and growth, which exhibits excellent compressible property and efficient adsorption performance of tetracycline. The loading capacity of ZIF-67 in ZIF-67/PAM/CSA can reach 42.7%, making the increased specific surface area up to 491.95 m2 g-1 for composite aerogel. For tetracycline adsorption, ZIF-67/PAM/CSA presents high capacity of 260.09 mg g- 1 as well as stable enough recycling availability. The composite aerogel synthesized here with high specific surface area and compressibility, offers a promising method to branch out compressible adsorbents with benefits for the adsorption regeneration process in pollutant treatment applications.
