摘要
以超高交联聚丙烯-苯乙烯-二乙烯基苯(PP-ST-DVB)纤维为母体,分别经磺化、氯甲基化和胺化反应制得强酸或强碱离子交换纤维;研究了在低湿条件下对酸碱有害气体的动态吸附性能。结果表明:强酸离子交换纤维(交换容量为2.92 mmol/g)对NH_3气体的穿透吸附量约为40.95 mg/g,高于Fiban K-1磺酸型离子交换纤维的穿透吸附量;强碱离子交换纤维对SO_2气体的穿透吸附量约为77.50 mg/g,是Fiban A-1强碱离子交换纤维的1.55倍,自制的强酸、强碱离子交换纤维可多次再生使用。
A strong-base or strong-acid ion exchange fiber was prepared using ultra high-crosslinked polypropylene-styrene-divi- nylbenzene （PP-ST-DVB） fiber as the matrix via sulfonation, chloromethylation and amination. Their dynamic adsorption properties for acidic and basic harmful gases were studied under low moisture condition. The results showed that the strong-acid ion exchange fiber with the exchange capacity of 2.92 mmol/g had the breakthrough adsorption about 40.95 mg/g for NH3 , higher than Fiban K-lsulfonic acid type ion exchange fiber; and the strong-base ion exchange fiber had the breakthrough adsorption about 77.50mg/g for SO2, 1.55 time higher than Fiban A-1 strong-base ion exchange fiber. The self-made strong-base and strong-acid ion exchange fibers can be recycled several times.
