“…To counteract the harmful effects of these metallic impurities, additives like glue [6][7][8] and gum arabic [9] are most commonly used, however, the search for better additives is continuing. For example, 2-butyne-1, 4-diol [10], nonylphenoloxylethelene [11] and a combination of nonylphenolpolyethylene glycol, dinaphthylamine-4,4 0 -disulphuric acid and polyethelene glycol [12,13] have been reported to be superior to glue or gum arabic.…”

A comparative study of the effect of 1-butyl-3-methylimidazolium hydrogen sulfate-[BMIM]HSO 4 and gelatine on current efficiency (CE), power consumption (PC), deposit morphology, and polarization behaviour of the cathode during electrodeposition of zinc from acidic sulphate solutions were investigated. Compared with the traditional industrial additive, gelatine, the addition of [BMIM]HSO 4 was found to increase current efficiency, reduce power consumption, and improve the surface morphology. Maximum CE and minimum PC were obtained at the addition dosage of 5 mg dm -3 . Meanwhile, simultaneous addition of the two additives induced a blocking effect of the zinc reduction and led to more leveled and fine-grained cathodic deposits. Moreover, cyclic voltammetry results and kinetic parameters such as Tafel slope, transfer coefficient, and exchange current density obtained from Tafel plots led to the conclusion that both additives have a pronounced inhibiting effect on Zn 2? electroreduction. The data obtained from X-ray diffractogram revealed that the presence of additives did not change the structure of the electrodeposited zinc but affected the crystallographic orientation of the crystal planes.

An Investigation on the Effects of Organic Additives on Zinc Electrowinning from Industrial Electrolyte

The influence of Saponin, Licorice, Tennafroth 250, and Dowfroth 250 at different concentration levels (0, 5, 10, and 15 ppm) were investigated during zinc electrowinning from industrially supplied spent electrolyte. Acid mist suppression efficiency, polarization behavior, current efficiency and energy consumption were investigated for a current density of 500 A.m -2 . Surface tension measurements were used to find a correlation between the concentration of the different additives and the acid mist suppression efficiencies. Morphological and crystallographic orientation studies indicated dense and well defined crystalline grains with homogeneous distribution mostly at the 5 ppm level of suppressant. Electrowinning in the presence of Saponin and Tennafroth was found to have high current efficiencies of 90% each with low energy consumptions of 2641 and 2675 kWh/t, respectively and the deposited crystals were found to be oriented preferably in the [101]

“…Examples here are glue and arabic gum which are the most commonly used additives in industry for the zinc electrowinning process [49,50]. However, in this particular study, additives were not employed since the MSA electrolyte also served to suppress the formation of dendrites and the particular focus was to examine the direct impact of current density on morphology in both the Hull cell and flow cell experiments.…”

AbstractThe Hull Cell was used to investigate the impact of current density j on the morphology and uniformity of zinc electrodeposited from a 2.5 mol dm −3 Zn 2+ solution in 1.5 mol dmmethanesulfonic acid at 40°C onto carbon-composite surfaces. The range of the applied deposition current density used was between 1 mA cm −2 and 100 mA cm −2 . Good, robust deposits were obtained when j ≥ 10 mA cm _2 whereas at j's lower than this, patchy films formed due to the competing hydrogen evolution reaction (HER) on the bare carboncomposite surface. An understanding of these effects and its application in the redox flow battery enabled both the coulombic and cell potential efficiencies to be maintained at relatively high values, 90% and 69% respectively, indicating a successful inhibition of the HER on the fully formed Zn layer. Flow velocity at the low Reynolds number in the cell (Re <200) had little impact on the electrochemical cell performance. Depletion of the cerium species became an issue for long charge times.
