| titleOfInvention | Preparation method of weak-acid cation chromatographic column filler exchange resin |
| abstract | The invention relates to a preparation method of weak-acid cation chromatographic column filler exchange resin of an ion chromatographic column. The exchange resin is used for preparing weak-acid cation chromatographic column filler. According to the invention, spherical silica gel base material, or PGMA/EDMA, PVA or PS-DVB exchange resin polymer microsphere base material firstly experiences a surface pre-agglomeration reaction with maleic anhydride and then is subjected to a regular grafting polymerization reaction to obtain exchange resin. The method provided by the invention solves the technical problems that ethylenediamine/tartaric acid leacheate is required for separating alkali metal and alkali metal ions at the same time and the system peak of the ethylenediamine influences the analysis result in the existing weak cation chromatographic column filler of exchange resin prepared by taking silica gel as a base body, the reaction process is relatively complicated and a Friedel-Crafts acylation reaction is needed before washing to remove chloride ions in the double-bond aliphatic weak-acid cation-exchange resin prepared by taking polymer microspheres as a base body, and the degree of separation and peak shape of the detection result of chromatographic column analysis of the filler prepared from the exchange resin are unsatisfactory. |
