| titleOfInvention | A kind of preparation method of chitosan or carboxymethyl chitosan functionalized nano selenium compound |
| abstract | The present invention relates to the synthetic method of a kind of chitosan or carboxymethyl chitosan functionalized nano selenium compound, belong to technical field of nano material.The inventive method includes：1) using sodium selenite as selenium source, KI is stabilizer, and sodium selenite stands aging with reducing agent ascorbic acid reaction a period of time (being specially 30min) and prepares nano selenium sol in 24 hours afterwards；2) obtained selenium sol mother liquor is washed by washing, alcohol, is centrifuged off impurity and obtains nano selenium sol；3) nano selenium compound that certain density chitosan or carboxymethyl chitosan obtain functionalization is added dropwise.The advantage of the invention is that：The preparation condition of nanometer selenium is simple, the particle diameter of the nanometer selenium of synthesis is small and uniform, good dispersion, the polysaccharide nano selenium compound of oppositely charged can be obtained by carrying out functional modification to its surface by chitosan and carboxymethyl chitosan, improve the stability and biocompatibility of nanometer selenium. |
