具有大的孔隙度和比表面积的大孔离子交换树脂,从开发至今约有十几年的历史。由于它兼具离子交换和吸附的功能,使离子交换树脂从过去主要用于单纯的离子交换单元过程发展到可应用于离子交换—吸附和吸附的单元过程,扩大了离子交换树脂的使用 With a large porosity and specific surface area of ​​the macroporous ion exchange resin, from the development so far about a dozen years of history. Because of its combination of ion exchange and adsorption, ion exchange resins have evolved from the past mainly for simple ion exchange unit processes to unitary processes that can be applied to ion exchange - adsorption and adsorption, expanding the use of ion exchange resins
