In this paper we report on the use of three ionic liquids, 1-methylimidazolium trifluoromethylsulfonate ([MIm]TfO), 1-ethyl-3-methylimidazolium trifluoromethylsulfonate ([EMIm]TfO) and 1-ethyl-2,3-dimethylimidazolium trifluoromethylsulfonate ([EMMIm]TfO) containing zinc trifluoromethylsulfonate as electrolytes for zinc electrodeposition. By varying the cations from [MIm](+)via [EMIm](+) to [EMM...
Zinc nanowires of serpentine geometry have been grown on conducting plastic and glass substrates in an aqueous electrolyte at an anomalously low temperature of 0 °C by a one-step, template-free electrodeposition technique. These nanowires are of several micrometers long and with a diameter of 20-200 nm. These nanowires are also single-crystalline and found to be coated with a 5 nm thick ZnO she...
in this study, the performance of electro-coagulation in combination with aluminum sacrificial anode, in removal of zinc and copper has been investigated. several parameters, such as pollutant concentration, ph, electrical potential, cod, turbidity and contact time were studied to achieve a higher removal capacity. variable concentrations (5-50-500 ppm) of zinc and copper solutions were prepare...
In this study, the designed dual stage membrane bioreactor (MBR) system was conceptualized for the treatment of cyanide and heavy metals in electroplating wastewater. The design consisted of a primary treatment stage to reduce the impact of fluctuations and the secondary treatment stage to remove the residual cyanide and heavy metal contaminants in the wastewater under alkaline pH conditions. T...
Rechargeable aqueous Zn/MnO2 battery chemistry in a neutral or mildly acidic electrolyte has attracted extensive attention recently because all the components (anode, cathode, and electrolyte) in a Zn/MnO2 battery are safe, abundant, and sustainable. However, the reaction mechanism of the MnO2 cathode remains a topic of discussion. Herein, we design a highly reversible aqueous Zn/MnO2 battery w...
Zinc and its alloy coatings are commonly used to provide cathodic protection for weathering steel. However, the steel substrate corrodes faster than coating because of coating's negative corrosion potential. Many studies have examined coatings' resistance corrosion. Hot-dip galvanizing, Electrodeposition, Zinc-rich coat (ZRC) spray just some methods that can be deposit such coatings. Commercial...
Nanoparticles of iron precipitates produced by a microbial consortium are suitable adsorbent for metal removal from electroplating industry wastewaters. Biogenic were utilized as adsorbents chromate and zinc in batch conditions. Furthermore, the embedded alginate beads fixed-bed columns, their performance was evaluated continuous system varying different operational parameters such flow rate, b...
Among the various existing metals, zinc and copper are predominant metals in several effluents from industries such as electroplating, plastics production mining. Technical methods have been applied treatment of containing including chemical removal, adsorption, ion exchange, membrane technologies electrochemistry. However, it is necessary to develop that minimize costs increase quality while r...
