poxopoBa等曾研究铜-丁二酮肟(DMG)-氨缓冲溶液体系的dc极谱行为。他们认为pH9.35,铜离子浓度3.5×10~(-4)M,DMG浓度≤7×10~(-4)M时是个扩散波(E_(1/2)?-0.3V);当DMG浓度较大时,波呈峰形(E_p?0.5V),是个催化氢波。他们尚未研究该体系的灵敏度及
PoxopoBa et al. studied the dc polarographic behavior of a copper-dimethylglyoxime (DMG) -amino buffer solution system. They think that the pH9.35 is 3.5 × 10 ~ (-4) M for copper ions and E_ (1/2) ~0.3V for DMG concentrations ≤7 × 10 ~ (-4) M) Concentration is larger, the wave was peaked (E_p? 0.5V), is a catalytic hydrogen wave. They have not yet studied the sensitivity of the system
