加工了用于研究萃取取动力学的高速搅拌反应装置(图1),并建立了相应的有机相分相和取样方法。反应容器体积为3.0cm×3.0cm×6.0cm。用聚丙烯短纤维作为分相物,它的亲油性大于亲水性,可很好将两相分开。用自制的分相器可连续取出高速搅拌时HNO3溶液/30%TBP-OK体系中的本体有机相,当转速为2500r/min、取样流量不大于8μL/s时,有机相样品中水的含量为0。 A high-speed stirring reaction device for the extraction kinetics was developed (Figure 1), and the corresponding phase separation and sampling methods were established. The reaction vessel volume was 3.0 cm x 3.0 cm x 6.0 cm. Polypropylene staple fiber as a phase separation, its lipophilicity is greater than the hydrophilic, it can be very good to separate the two phases. The homemade organic phase in HNO3 solution / 30% TBP-OK system at high speed stirring can be taken out continuously with a homemade phase separator. When the rotation speed is 2500 r / min and the sampling flow rate is not more than 8 μL / s, the water content in the organic phase sample Is 0
