一般說明

二甲基乙二肟(DMG)是一种络合配体。 二甲基乙二肟可与带有诸如VO(IV)、Ni(II)、Zn(II)、Pd(II)、Cd(II)和Pb(II)等金属的N-乙酰基甘氨酸形成许多混合配体络合物。它是用于分光光度法测定Co(II)、Fe(II)、Ni(II)、Pd(II)和Re(VII)的有效试剂。

應用

二甲基乙二肟(DMG)被用作钴(II)和镍(II)金属的络合剂,可用于通过吸附溶出伏安法分析盐水中的痕量金属。 在一项研究中,DMG已被用于开发一种新型DMG,其包含改性溶胶-凝胶碳复合电极,从而用于重金属伏安传感测定中。

Dimethylglyoxime (DMG) adsorbed on Au(111) was investigated using electrochemical scanning tunneling microscopy (STM) and X-ray photoelectron spectroscopy (XPS). STM experiments revealed three different structures of adsorbed DMG at open circuit potential (~0.07 V versus Ag/AgCl): (2√3×2√3)R30°-α, (2√3×4√3)R30°-β, and (2√3×4√3)R30°-γ. The
