Electrodeposition of Iron Films on Copper Surfaces from Iron(III) Gluconate Solutions

Influence of Chloride and Sulfate Ions on Electrodeposition, Wettability and Corrosion Resistance of Zinc Coatings Produced from Gluconate Solutions

“…Sodium gluconate is a cheap and environmentally safe additive having good buffering properties and forming soluble complexes with many metal cations in either acidic or alkaline baths. [26][27][28][29][30][31][32][33][34] Gluconatebased solutions were introduced to the zinc plating in late 1960-ties in Japan, 29 however, up to date only a few more reports on the zinc electrodeposition from only sulfate-gluconate baths were published. [30][31][32][33] z E-mail: erudnik@agh.edu.pl They were focused on basic characterization of the zinc coatings produced at various electrolysis conditions 29,31 and in a presence of organic additives 32 as well as on electroreduction of zinc species.…”

Electrodeposition and Growth of Iron from an Ethylene Glycol Solution

“…The electroreduction and electrodeposition of iron ions have been reported. [12][13][14][15][16][17][18] The results presented in the previously published work 12 showed that the electrodeposition of iron in an acidic sulfate medium occurred, at least, through three adsorbed intermediates. It was observed that on the nonlinear part of the polarization curves, the electrodeposition of iron occurred, but with very low efficiency.…”

“…Iron metal films were also electrodeposited on copper substrates by the galvanostatic method at various pH, temperature, and current density from weak acidic (pH = 5.7) solutions containing iron sulfate and sodium gluconate. 16 It was found that the optimal conditions for obtaining stable Fe films are as follows; a solution consists of 0.038 mol • dm 3 Fe 2 (SO 4 ) 3 .7H 2 O and 0.14 mol•dm 3 sodium gluconate, at current density (j) = 0.33 A / cm 2 , pH = 5.7, and temperature 25 °C. The obtained Fe films from this electrolyte have a single-phase crystal structure.…”
