中文摘要: 在恒界面池中研究DIBK-TBP协同萃取体系萃取铪、锆的动力学，考察了温度、界面积和搅拌强度等对萃取速率的影响。结果显示，DIBK-TBP体系萃取铪和锆的过程符合一级动力学反应；对铪的萃取为相内反应和扩散共同影响的混合控制类型，表观活化能-43.106 kJ/mol；对锆的萃取与搅拌强度、比界面积无关，为相内反应控制类型，表观活化能-16.024 kJ/mol。
Abstract:The extraction kinetics of synergistic extraction system of DIBK-TBP for hafnium and zirconium were studied in constant interface pool. The effects of temperature, interfacial area, and stirring speed on extraction rate of hafnium and zirconium were investigated. The results show that extraction process of hafnium and zirconium in DIBK-TBP system fits with pseudo-first order reaction. Affected by inner phase reaction and diffusion, the extraction process of hafnium is mix-controlled with apparent activation energy of -43.106 kJ/mol. Under no influence of stirring speed and interfacial area, the extraction process of zirconium is inner phase reaction control type with apparent activation energy of -16.204 kJ/mol.
