| titleOfInvention | A kind of preparation method and application of the polyvinyl alcohol crosslinked affinity membrane of macropore chitosan of chelated metal ions |
| abstract | The present invention relates to a kind of preparation method and applications of the polyvinyl alcohol crosslinked affinity membrane of macropore chitosan of chelated metal ions.The preparation of film includes：Chitosan, polyvinyl alcohol, silica gel carry out being mixed to prepare chitosan polyvinyl alcohol film；Drilling is handled using sodium hydroxide solution；It is added into epoxychloropropane and sodium hydroxide, obtains the polyvinyl alcohol crosslinked film of macropore chitosan of network structure；It is dipped in into the sodium carbonate liquor containing iminodiacetic acid；The film after drying is immersed into the solution containing bivalent metal ion again, it can obtain the polyvinyl alcohol crosslinked affinity membrane of macropore chitosan of chelated metal ions, it has stronger mechanical strength, and has efficient affine adsorption capacity to the protein containing histidine.It is applied to the separation rich in histidine protein matter or enzyme, it is main prepared including crude enzyme liquid, film to the specific affine absorption rich in histidine protein matter or enzyme, the elution of adhesion protein, film regeneration Four processes. |
