The voltammetric behaviour of nitrosodimethylamine (NDMA) on lead electrode in 1.OM H2SO4 indicates that it is reduced in a 48 stel, to unsymmetrical dimethyl hydnine (UDMH) as in the case of eatii polerographii works on Hg electrodes. Hdwver the electron transfer rate is much slower on Pb electrode and the first electron-transfer step is the rate determining step. Thim is in contrast to the beheviiur on Hg where the charge transfer is totally reversible. At higher NDMA concentrations some inhibiting adsorption effects are also noticed. Addition of UDMH to 1 .OM H1S04 results in substantial positive shift of the hydrogen evolution potential. In presence of UDMH (3 500 mM) the hydrogen evolution process takes plece at the potential where nitrosodimethylamine itself is reduced. This parallel compedth hydmgen evolution process explains the sudden drop in current efficiency in the preparative scale for the electroreduction of NDMA.
