摘　　要：目的:研究泡沫浮选法用于青黛分离的间歇式操作工艺。方法:以靛蓝回收率、纯度比为评价指标,对气流速度、进料浓度、pH、进料体积等操作参数进行单因素考察,研究其对泡沫浮选效果的影响。结果:在112 L/h^256 L/h范围的变气速操作,浓度为0.4 g/mL的粗靛浆液,不调pH值,进料体积为1000 mL时,以靛蓝计纯度比为2.3左右,泡沫中靛蓝回收率达到90%左右。结论:泡沫浮选技术应用于青黛分离工艺稳定可行。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.
