Abstract:
Objective To investigate chitosan flocculating and other pretreatments of Huoxue Tongluo extract and their effects on the membrane flux and fouling degree of membrane. Methods Based on the index related to the total sinomenine reserved in liquid and fouling degree of membrane, compared to other pretreatments, discuss the function of chitosan used as flocculation and the effect on membrane separation by orthogonal test. Results The reservation of the total sinomenine was best by means of chitosan flocculation and the smallest fouling degree of membrane was it too, compared with other pretreatments as decompress filtration, high-speed-centrifugation, low-speed-centrifugation and decolored by active carbon. Conclusion Chitosan flocculating is the best pretreatment method of Huoxue Tongluo extract, and the suggested operation condition is that the Huoxue Tongluo extract’s temperature is 50 ℃, pH=5 and add 1% chitosan 30 mL/L.
