ELECTRODEPOSITION OF PROTACTINIUM SOURCE IN NH4F ELECTROLYTELi Zongwei(Institute of Modern Physics, The Chinese Academy of Sciences, Lanzhou 730000)ABSTRACTThe experimental method for preparation of thin and uniform Palayers in the solution of NH4F 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 Palayer of 1 mg/cm2 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 233Pa NH4F electrolyte
