General description

Dimethylglyoxime(DMG) is a complexing ligand. Dimethylglyoxime forms a number of mixed ligand complexes with N-acetylglycine and various metals such as VO(IV), Ni(II), Zn(II), Pd(II), Cd(II) and Pb(II).

Application

Dimethylglyoxime (DMG) was used as complexing agent for the quantification of metallic impurities [cobalt(II) and nickel(II)] in brine (5.5mol/l aqueous solution of sodium chloride) by adsorptive stripping voltammetry. DMG may be used as ligand in the fabrication of modified sol-gel carbon composite electrodes, which can be employed for the detection of trace levels of heavy metals.
