| Abstract: | The method of preparing low-molecular-weight of the CM-chitosan is studied, which hydrogen- peroxide is involved. The various factors such as the density of the hydrogen-peroxide , the dosage and reaction temperature and time are discussed. The optimal procedure to prepare the low-molecular-weight CM-chitosan was determined. |
