合成的共聚物和生物聚合物，以及强酸离子交换剂，在无机盐的存在下，以获得具有高比表面积和良好的吸附和机械性能的珠状产品。苯乙烯-二乙烯基苯阳离子交换剂和丙烯腈-DVB共聚物被认为是聚合物分子筛的最佳原料。对所制备材料的孔结构和吸附性能进行了表征。离子交换剂的吸附容量与木材制备的活性炭相当。(C)2001爱思唯尔科技有限公司版权所有。
Synthetic copolymers and biopolymers, as well as strong acid ion exchangers, were carbonized in the presence of inorganic salts to obtain products in bead form with a high specific surface area and good sorption and mechanical properties. Styrene-divinylbenzene cation exchangers and acrylonitrile-DVB copolymers were found to be the best starting materials for polymeric molecular sieves. The porous structure and sorption properties of prepared materials were characterized. The sorption capacities of carbonized ion exchangers are comparable with those of activated carbon prepared from wood. (C) 2001 Elsevier Science Ltd. All rights reserved.
