在 NH_4F 介质中电沉积 ~(233)Pa 源

  • 摘要: 介绍了在NH4F介质中制备薄而均匀的233Pa镀层的实验方法。对233Pa电沉积的主要影响因素(电流密度、搅拌速度、电镀时间和溶液的pH等)进行了实验,得到了在不锈钢片上电沉积厚度为1mg/cm2的233Pa源。同时观察了用不同阴极材料对电沉积233Pa源厚度及电沉积效率的影响,提出了在不锈钢片上制备233Pa源的工艺流程。

     

    Abstract: ELECTRODEPOSITION OF PROTACTINIUM SOURCE IN NH4F ELECTROLYTELi Zongwei(Institute of Modern Physics, The Chinese Academy of Sciences, Lanzhou 730000)ABSTRACTThe experimental method for preparation of thin and uniform Palayers in the solution of NH4F is studied. The main factors, including current density, stirring rate, electroplating time and pH value of solution which influence the electrodeposition of Pa are experimented. The influence of different anode materials with the thickness and efficiency of electrodeposition source is also observed. The electroplating Palayer of 1 mg/cm2 thickness on thin stainless steel disk is obtained. The industrial procedure of Pa preparation in the stainless steel plate is given.Key words electrodeposition method 233Pa NH4F electrolyte
