[Preparation of monodispersed agglomerated pellicular cation exchange resins and its chromatographic properties].
A new and simple method for the preparation of latex-coated pellicular cation exchanger is introduced. Chromatographic stationary phase of monodispersed agglomerated pellicular cation was prepared for the first time. The monodispersed polyvinylbenzene-divinylbenzene (PSTDVB) particles (10 microns) as substrate beads were functionalized with a tertiary amine on the surface at first and then attached with a layer of sulfonated latex particles (0.2 micron) to give the desired packing. Its chromatographic properties were evaluated by using alkali metals (Li+, Na+, NH4+, K+) and alkaline earth metals (Mg2+, Ca2+). The results showed that the packing is of good resolution, low detection limit, and excellent repeatability for common inorganic cations.
