“…The influence of added cadmium, iron and nickel chlorides on the current efficiency, and on the nature of the deposit, has been a subject of numerous investigations in the past (40,41,51,62,65). Only a modest effort was devoted to this problem area in the present investigation.…”

“…Many authors have neglected consideration of systematic errors in their measurements of the current efficiency (41,46,62). To evaluate the systematic errors in this study, two independent methods for determining the amount of zinc deposited were used: weight measurements and EDTA titration.…”

“…Cadmium [7] did not affect the growth or orientation of the zinc deposit but reduced the deposit grain size. Small concentration of germanium [6,14,15] and tin [16] drastically reduced the CE and induced changes in cathodic polarization, deposit morphology and crystallites orientation. Antimony [1,2,[17][18][19] was recognized as one of the most deleterious impurities for zinc electrodeposition whose presence in the electrolyte produced spongy and dark deposits.…”

The effects of ionic liquid additive 1-butyl-3-methylimidazolium hydrogen sulfate- [BMIM]HSO 4 on the current efficiency (CE), surface morphology, and crystallographic orientations during zinc electrodeposition from acidic sulfate solutions containing some common impurities such as copper, iron, cobalt, nickel, and lead were investigated. The results indicated that all the metallic impurities studied exerted a deleterious effect on the zinc electrodeposition process by decreasing the CE, influencing the purity, and inducing changes in morphology of the cathodic deposits. The addition of [BMIM]HSO 4 was observed to relieve the harmful effects of these impurities to some extent, and led to reduce the impurity content in the zinc deposits and improve the CE and the quality of the cathodic deposits. The data obtained from X-ray diffraction revealed that the presence of these impurities alone and in combination with [BMIM]HSO 4 did not change the structure of the electrodeposited zinc but affected the crystallographic orientation of the crystal planes.

“…Up to now, there have been a large number of research reports investigating the effects of various metallic impurities on zinc electrodeposition, which includes copper, [1][2][3] iron, [2][3][4] cadmium, [2] germanium, [5][6][7] manganese, [8,9] cobalt, nickel, [10][11][12] and so on. It has been reported that, although these metallic impurities have great influence on the zinc electrodeposition, most of them can be removed through the purification process.…”

The effects of Mg 2+ ion on the zinc electrodeposition were systematically investigated in sulfuric acid solution through the characterizations of current efficiency (CE), power consumption (PC), deposit morphology, cathodic polarization, and cyclic voltammetry. The results demonstrate that there is no significant influence on CE and PC in the Mg 2+ concentration range of 1 to 10 g L À1 , but with a drastic decrease of the CE and rapid increase of PC at Mg 2+ ion concentration above 15 g L À1 . Based on the morphology observation and polarization curves, the presence of Mg 2+ ions could also induce the coarse surface on the electrodeposited zinc accompanying the enhancement of the cathodic polarization, which becomes more distinct at a high concentration above 15 g L À1 . Furthermore, hydrogen evolution could be promoted with the existence of Mg 2+ ions according to cyclic voltammograms.
