Objective: To analyze reasons why transfer rates of small molecules substances were different through Al2O3 ceramic membrane. Method: Taking four kinds of small molecules effective substances in Huanglian Jiedu decoctions as object of study
computer simulation technology was adopted to analyze interaction between four kinds of effective substances and Al2O3 ceramic membrane
then confirmed by experimental results. Result: Al2O3 ceramic membrane showed some adsorption on berberine hydrochloride
palmatine chloride
baicalin and jasminoidin
transfer rates were 94.21%
90.17%
83.71%
85.61%;adsorption energies were -101.451
-548.142
-797.793
-792.970 kcal·mol-1. Conclusion: Difference of adsorption energies may be main causes of different transfer rates in membrane process.
