Abstract:
Objective To study the process of foam fractionation of polyphyllin in semi-batch mode. Methods Taking enrichment ratio, recovery rate of polyphyllin, and purity ratio as the performance criteria and using single examining method to examine the operational parameters, i.e. operation mode, air flow rate, initial feed concentration, solution pH value, initial feed height and temperature on separation performance. The optimal conditions of the process were obtained finally. Results The separation performance is good when gas flow rate is 400 mL/min, initial feed concentration (polyphyllins content) is 0.3 mg/mL, pH value is 7, feed height is 30 cm, and feed temperature is 40 ℃. The enrichment ratio is 25.7, recovery ratio is 42.1%, and the foam liquids purity of total polyphyllin is 41.4%, which is 4.5 times higher than that in feed purity. Conclusion Foam fractionation technique could be applied to separate polyphyllin.
