摘　　要：以四甲基对苯二甲腈氧化物和乙烯基硅氧烷为原料,通过点击聚合成功制备出含有硅氧烷基团的异恶唑啉基多孔聚合物(PSIPP)。由于PSIPP的疏水性及其与TNT之间的路易斯酸碱作用、偶极-π相互作用和π-π相互作用,PSIPP对TNT的吸附容量可达161 mg/g,吸附平衡时间为14 h,且在5种不同污染水样中对TNT也有很好的吸附性能;经过5次吸附-解吸循环后,对TNT的吸附量仍能达到最大吸附量的85%以上,表明PSIPP具有良好的循环使用性能;质量浓度200 mg/L的TNT溶液经PSIPP 5次吸附处理后可达到国家安全排放标准。异恶唑啉基多孔聚合物可用于TNT污染水的处理。Isoxazoline-based porous polymer(PSIPP)containing siloxane groups was successfully synthesized through click polymerization by using tetramethylterephthalonitrile oxide and vinyl siloxane as raw materials.Due to the hydrophobicity of PSIPP and the Lewis acid-base interaction,dipole-πinteraction andπ-πinteraction between PSIPP and TNT,the adsorption capacity of PSIPP for TNT could reach 161 mg/g,and the adsorption equilibrium time was 14 h.At the same time,PSIPP had good adsorption properties for TNT in five different polluted water samples.After 5 adsorption-desorption cycles,the adsorption capacity of TNT could still reach more than 85%of the maximum adsorption capacity,showing PSIPP had good recycling performance.TNT solution with a mass concentration of 200 mg/L,which was absorbed by PSIPP five times,could meet the national safety discharge standard.Theisoxazoline-based porous polymer can be used for the treatment of TNT contaminated water.
