The effect of tert-butanol adsorption on the two-step electroreduction of Zn2+ and its dependence on the NaClO4 concentration

Mixed adsorption layers of 0.1 M tert-butanol–tetramethylthiourea at the interface of Hg/aqueous perchlorate solutions

“…The molecular structure of both organic substances having hydrophobic methyl groups allows us to expect that vertical orientation of their molecules may change insignificantly. The investigated substances have an inverse effect on the kinetics of electroreduction of Zn 2+ ions [16,17]. The adsorption parameters presented in the paper concerning the formation of mixed adsorption layers will be used in studies of kinetics and the mechanism of electroreduction of Zn 2+ ions in the presence of TB and TMTU.…”

The Influence of tert-Butanol on a Two-step Zn2+ Ion Electroreduction in Concentrated NaClO4 Solutions

“…The influence of NaClO 4 concentration on Zn 2+ electroreduction in presence of tert-butanol was investigated recently but it concerned diluted solutions. 9 The present paper is a continuation of this problem referring to 2, 3, and 4 mol dm -3 NaClO 4 . The results obtained are a compilation of tert-butanol adsorption and Zn…”

“…9 The base electrolyte concentration influences the degree of Zn 2+ ion aquacomplexes and electrode surface hydration and hence on the depolarizer electroreduction kinetics. The influence of NaClO 4 concentration on Zn 2+ electroreduction in presence of tert-butanol was investigated recently but it concerned diluted solutions.…”

Electrochemical Studies and Extraction of Chemical and Electrochemical Parameters of Zn(ii) Ion at Mercury Electrode via Convolutive Voltammetry and Digital Simulation Methods

“…[12][13][14] The electroreduction of Zn from NaClO 4 solutions at a mercury electrode in the presence of tert-butanol is supposed to involve two consecutive one-electron transfer steps in the overall reaction. 6 The kinetics of the electroreduction of zinc cations in non-aqueous solvents such as DMF 15 , DMSO 16 and acetone 17 were found to proceed as simple and two step processes.…”

“…[1][2][3][4][5][6] At mercury electrode different mechanisms have been proposed for electrode reduction of metal cations, e.g., a simple electron transfer process 7,8 , stepwise electron transfer 9 , a CE or CEE mechanism. 10,11 Several literature reports a possible validity of a mechanism involving two one-electron transfer has been discussed.…”
