Abstract:
AIM:To optimize the flocculation-clarification process of Danshen aqueous extract.METHODS:Based on the single factor experiment,the turbidity of the index components danshensu,protecatechnic aldehyde concentration in the Danshen aqueous extract after flocculation were choose among the kinds and amount of flocculant and flocculation temperature.RESULTS:The turbidity of the chitosan-treated supernatant was lower than that of the ZTC1+1Ⅱ-treated ones,and this treatment can mitigate the membrane fouling better.CONCLUSION:Chitosan is superior to ZTC1+1Ⅱ as the flocculant of the Danshen aqueous extract.
