Article Synopsis
- This study explores the use of vapor permeation membrane technology to separate essential oils from an oil-water extract derived from Forsythia suspensa.
- Two types of membrane materials, PDMS/PVDF composite and PVDF alone, were compared in terms of their efficiency in extracting essential oil.
- The findings indicated that the PVDF membrane yielded significantly more essential oil and had a chemical composition that closely resembled traditional steam distillation methods, suggesting its superior suitability for this application.
In order to explore the adsorption characteristics of proteins on the membrane surface and the effect of protein solution environment on the permeation behavior of berberine, berberine and proteins were used as the research object to prepare simulated solution. Low field NMR, static adsorption experiment and membrane separation experiment were used to study the interaction between the proteins and ceramic membrane or between the proteins and berberine. The static adsorption capacity of proteins, membrane relative flux, rejection rate of proteins, transmittance rate of berberine and the adsorption rate of proteins and berberine were used as the evaluation index.

- * Four key factors were examined: inlet temperature, liquid density, feed rate, and air flow rate.
- * Findings indicate that varying these conditions leads to differences in the powder's morphology and adsorption, with the best results achieved at an inlet temperature of 150°C, a feed density of 1.05 g/mL, a feed rate of 20 mL/min, and an air flow rate of 30 m³/h.
