摘要：
A complexation extraction-back extraction method was established to separate isoliquiritigenin in the licorice ultrafiltrate. Through single factor and factorial design experiments, the best complex extractant and stripping agent were obtained respectively by observing their effects on the extraction rate and the back extraction rate of isoliquiritigenin. The optimized ternary complex extractant composition was 0.5% trialkylphosphine oxide +10% tributyl phosphate + 89.5% sulfonated kerosene, the extraction rate was 99.23% and the recovery rate was 100% after extraction. The optimized stripping agent was 0.010 0 mol∙L-1 NaOH aqueous solution, the stripping rate was 97.85% and the recovery rate was 95.11% after back extraction, the total recovery rate was 95.11%. Results show that the isoliquiritigenin in the licorice ultrafiltrate could be transferred in complex extractant and stripping agent with high extraction efficiency. It is possible to apply complex extraction-back extraction method for the separation of isoliquiritin in licorice ultrafiltrate. © 2020, Editorial Board of "Journal of Chemical Engineering of Chinese Universities".
