Abstract:
AIM: To study the process of foam floatation in the separation of Indigo Naturalis in batch mode. METHODS: Recovery of indigo and purity were chosen as the performance criteria and single examining method to examine the operational parameters,i.e.air flow rate,initial feed concentration,solution pH,initial feed volume on floatation performance. RESULTS: The floatation performance was good when gas flow rate increased from 112 L/h to 256 L/h,initial feed concentration of 0.4 g/mL,keeping the initial pH,feed volume of 1 000 mL.The purity ratio of indigo was about 2.3 and the recovery was about 90%. CONCLUSION: Foam(floatation) can be applied to the separation of Indigo Naturalis.
