摘　　要：The mass-transfer kinetics of ytterbium between aqueous solutions and heptane solutions of CA- 12 and CA-12-HEHEHP have been studied by using a constant interfacial area cell with laminar flow. The results have been interpreted according to a series of reversible interfacial reactions. In this work, it has been discovered that HEHEHP can increase the rate of ytterbium extraction by CA-12.The mass-transfer kinetics of ytterbium between aqueous solutions and heptane solutions of CA- 12 and CA-12-HEHEHP have been studied by using a constant interfacial area cell with laminar flow.
