| titleOfInvention | A kind of polysaccharide iron with controllable molecular weight and preparation method thereof |
| abstract | The invention discloses a preparation method of polysaccharide iron with controllable molecular weight, which is characterized in that it comprises the following steps: (1) the step of preparing an aqueous colloidal solution comprising Fe(III) ions and (OH ) ions, controlling the colloidal The particle size of the ferric hydroxide sol in the aqueous solution is 4-10nm; (2) the step of heating up to 30-75°C and adding polysaccharides for pre-complexation reaction; (3) the pre-complexation product is complexed at 110-130°C The steps of the combined reaction. Its molecular weight distribution range is narrow and the molecular weight is controllable. |
