吸附树脂就是树脂吸附剂,特征是具有吸附功能,是利用树脂能发生吸附——解吸作用,以达到物质的分离净化目的的一类可以反复使用的树脂。一般是按照制备大孔型离子交换树脂骨架的方法制得,未经功能基反应,大多数不带离子交换基团的多孔性树脂骨架,外观多半是不到一毫米的白色小颗粒;有些由带极性基团的单体制得,也就是离子交换树脂,两者很难严格区分。吸附树脂和活性炭、氧化铝、硅胶等吸附剂的作用很相象,又不相同。它的特
Adsorption resin is a resin adsorbent, characterized by adsorption, is the use of resin adsorption-desorption can occur, in order to achieve the purpose of separation and purification of substances can be a reusable resin. Generally in accordance with the preparation of macroporous ion exchange resin framework prepared by the system, without functional group reaction, most non-ion exchange groups of porous resin skeleton, the appearance of mostly less than one millimeter of white small particles; some by Polar group with the monomer obtained, that is, ion exchange resin, the two are difficult to strictly distinguish. Adsorption resin and activated carbon, alumina, silica gel and other adsorbent role is very similar, not the same. It’s special
