詳細

詳細

Dimethylglyoxime (DMG) is a complexing ligand. Dimethylglyoxime forms a number of mixed ligand complexes with N-acetylglycine with metals such as VO(IV), Ni(II), Zn(II), Pd(II), Cd(II) and Pb(II). It is a useful reagent for the spectrophotometric determination of Co(II), Fe(II), Ni(II), Pd(II) and Re(VII).

アプリケーション

Dimethylglyoxime (DMG) was used as complexing agent for cobalt(II) and nickel(II) metals for the analysis of brine for trace metals by adsorptive stripping voltammetry. DMG was used in a study to develop a new DMG containing modified sol-gel carbon composite electrode for voltammetric sensing of heavy metals.
