Conductivity, Electrodeposition and Magnetic Property of Cobalt(II) and Dysprosium Chloride in Zinc Chloride-1-Ethyl-3-Methylimidazolium Chloride Room Temperature Molten Salt
Electric conductivity of the molten zinc chloride-1-ethyl-3-methylimidazolium chloride phases has been measured by a computerized system using the d.c. four-probes method. The sequence of the conductivities for the different component melts is ZnCl2-EMIC > ZnCl2-EMIC-CoCl2 > ZnCl2EMIC-DyCl3 > ZnCl2-EMIC-CoCl2-DyCl3. The results may be explained in terms of the viscosity increase due to the comp...
متن کاملGreen extraction of Niobium and Tantalum from Kenticha Tantalite ore using 1-Ethyl-3-Methyl Imidazolium Chloride ionic liquid
The decomposition of the Ethiopian Kenticha tantalite ore was studied using the KOH fusion and H2O leaching system at 400 0C for a 1 h reaction time. The experimental results obtained showed that 27 wt% of Ta2O5 was mainly transformed into insoluble KTaO3, not to be KNbO3, and as well, into the dissolved liquor containing 94.73 vol% of Nb2O5 and 75.80 vol% of Ta2O5. The observations, supported ...
متن کاملXAFS STUDIES OF Ni, Ta AND Nb CHLORIDES IN THE IONIC LIQUID 1-ETHYL-3- METHYL IMIDAZOLIUM CHLORIDE / ALUMINUM CHLORIDE
The structure of anhydrous nickel, niobium and tantalum metal chlorides in ionic liquids IL) is important in the development of new electrochemical alloy deposition techniques. In order to understand the interactions of these metal ions with ionic liquids, we have investigated their structures in situ with X-ray Absorption Spectroscopy (XAS). The ionic liquid used in this study is 1-methyl-3-et...
متن کاملElectrodeposition of Zinc From Low Temperature Molten Salt Electrolyte: Part I-Imidazole And Zinc-Chloride Electrolyte
Our R & D work was focused on the electro deposition of Zinc from imidazole as low temperature molten salt (LTMS) electrolyte with zinc chloride as a supporting salt at <100o C., without required controls from the previous existing non aqueous baths as well additive free system for the zinc deposition. Surface morphological studies and crystallographic orientation results were evaluated.
متن کاملNonanomalous Electrodeposition of Zinc-Iron Alloys in an Acidic Zinc Chloride-1-ethyl-3-methylimidazolium Chloride Ionic Liquid
The electrodeposition of iron and Zn-Fe alloys on polycrystalline nickel was investigated in the 40.0-60.0 mol % zinc chloride1-ethyl-3-methylimidazolium chloride ionic liquid containing iron~II! at 90°C. Iron~II! was electrochemically reduced to iron metal before the reduction of zinc~II! to zinc metal, and anomalous codeposition of Zn-Fe did not occur in this ionic liquid. Underpotential depo...
