Abstract
N,N'-Dimethyl-, N,N'-diethyl-, N,N'-diisopropyl- and N,N'-dibutylthiourea increase the rate of Zn(II) electroreduction in 1 M NaClO4. Increasing size of alkyl radical for the successive derivatives causes increase of their adsorption on mercury which, in turn, causes the increase of Zn(II) electroreduction rate. Electroreduction rate is also influenced by the change of molecule orientation on the electrode.
