| titleOfInvention | A kind of preparation method of cornstalk core regenerated polysaccharides etherate plural gel |
| abstract | The present invention discloses a kind of preparation method of cornstalk core regenerated polysaccharides etherate plural gel, this method removes the peel air-dried maize straw, grind and screening obtains acceptable material, after its benzene alcohol liquid extracting is handled, delignification processing is carried out using acid sodium chlorite method, dry polysaccharide is then dissolved in low temperature sodium hydroxide（Lithium hydroxide）/ urea（Thiocarbamide）Centrifuged in liquid after bubble removing, sulfuric acid solution is added dropwise and is adjusted to neutrality, sediment is centrifuged, cleans, dried, and obtains regenerated polysaccharides；Etherification reaction is carried out with regenerated polysaccharides respectively using two kinds of etherifying agents of anions and canons, two kinds of anions and canons regenerated polysaccharides etherates are obtained；Finally, two kinds of etherification products are dissolved, epoxychloropropane liquid is added dropwise and carries out cross-linking reaction, cornstalk core regenerated polysaccharides derivative plural gel is made；The obtained white microspheroidal of gel, has higher adsorption capacity, and with biodegradability, belong to environmentally friendly organic dyestuff sorbing material to methylene blue and crystal violet. |
