Application of Modified Chitosan for Treatment of Silk Degumming Wastewater

Abstract:

Chitosan was modified by 2,3-epoxypropyl trimethyl ammonium chloride (ETA) to prepare 2-hydroxypropyltrimethyl ammonium chloride chitosan (HACC) with good water-solubility. The optimum process of modification was studied. Then the HACC was used as coagulant to treat silk degumming wastewater and recycle sericin. The result showed that the HACC with over 90% degree of substitution had high performance for treating the wastewater, which could be prepared by controlling the reaction temperature at 70°C, molar ratio of ETA to chitosan at 3:1, reaction time for 8 hours and pH at 8. When it was used to treat the degumming wastewater, the optimum treating process was 8 for pH value and 1 g/L of coagulant.
