    Abstract: A method for measuring the uranium concentration of an aqueous solution including the following successive steps: a) electrochemical reduction towards valence IV, of the uranium present in the aqueous solution with a valence greater than IV, this reduction being implemented at pH

    Abstract translation: 一种用于测量水溶液的铀浓度的方法,包括以下连续步骤:a)以大于IV的价态在水溶液中存在的铀的IV价态电化学还原,该还原在pH <2和 在溶液中流过电流; b)在640和660nm之间,优选652nm的选定波长下测量在步骤a)完成后得到的溶液的吸光度; 以及c)通过从步骤b)中获得的吸光度的测量中扣除在步骤a)完成后得到的水溶液中存在的铀浓度(Ⅳ)来确定水溶液的铀浓度。
