本文研究了铀与PMBP形成络合物的极谱行为,并建立了痕量铀的极谱测定方法。该方法灵敏度高,用于地质样品分析可获得满意结果。 In this paper, the polarographic behavior of complexes formed between uranium and PMBP was studied and a polarographic method for the determination of trace uranium was established. The method has high sensitivity and can be used to obtain satisfactory results for geological sample analysis.
