反渗透技术在鼻炎康等中药提取液浓缩中的应用

Concentration of extraction solution of Biyankang and other traditional Chinese medicine by reverse osmosis process

以中药鼻炎康提取液、复方珍珠暗疮提取液和VC银翘提取液为研究对象,研究反渗透技术在提取液浓缩过程中的应用.试验结果表明,经反渗透工艺能有效脱水60%以上,中药的主要有效成分保留率达90%,膜通量稳定在14L/(m2.h),清洗后膜通量恢复80%以上.

The concentration of extraction solution of traditional Chinese medicine by reverse osmosis process was studied, while Biyankang, Pearl acne and Vitamin C Yin Qiao were as sample. The results show that the dehydration rates of these medicines were more than 60%, the membrane flux was more than 14 L/（m2· h）, and recovery of membrane flux is more than 80% after chemical cleaning,
