摘　　要：以30%TRPO/煤油溶液和1mol/L HNO_3溶液为体系,研究气提泵在柱径100mm喷嘴板脉冲萃取柱中的应用规律。实验结果表明:设计的水相进料气提泵、有机相进料气提泵和水相出料气提泵的液体流量和气体流量均满足线性操作;特别是脉冲萃取柱分散相存留分数与水相吹口气提泵的浸没度之间也呈线性关系,并结合吹气法在线测量技术,可实现对脉冲萃取柱稳定操作进行有效控制。The present research aims to determine the application of air-lifting pump in 100 mm diameter standard spray-sieve-plates pulsed extraction column for 30%TRPO/ kerosene solution-1 mol/L HNO3 solution. The liquid flow rate of air-lifting pump, designed for aqueous phase feeding, organic phase feeding and aqueous phase discharging, increases linearly with air flow rate within experimental range, and the submerged ratio of the air-lifting pump for aqueous phase discharging is linear with the holdup of the pulsed extraction column. By combining above results with the online measurement of air-purge method, the steady state of pulsed extraction column is easily controlled.
