钚可在草酸铵、硫酸铵以及氯化铵等体系中电沉积,草酸铵体系需加热且pH值不稳定,氯化铵体系产生氯气腐蚀不锈钢片,因此本工作选用体系稳定的硫酸铵体系来电沉积制备钚靶。操作流程如下:将Pu溶液加入到一定浓度的硫酸铵溶液中,用浓氨水调节体系pH值,电沉积一定时间后,将pH值调至6,继续电沉积5 min Plutonium electrodeposition in ammonium oxalate, ammonium sulfate and ammonium chloride and other systems, ammonium oxalate system to be heated and the pH value is unstable, the ammonium chloride system produces chlorine corrosion of stainless steel, so the selection of the system stable ammonium sulfate system call Deposition of plutonium target. The operation flow is as follows: the Pu solution was added to a certain concentration of ammonium sulfate solution, with concentrated ammonia to adjust the pH of the system, after a certain period of electrodeposition, the pH value was adjusted to 6, the electrodeposition was continued for 5 min
