Isolation and Structural Characterization of Alkali and Alkaline Earth Metal Salts with Synthetic Non Cyclic Ionophores
In the present study, an investigation on the complex formation between mono- and divalent metal ions (Na+, K+, Li+ and Mg2+) in the form of salt with different podands using various solvents has been carried out. Isolated complexes were characterized by different spectroscopic techniques viz. IR, NMR and elemental analysis. On the basis of ...
متن کاملInvestigation of performances of solvents D2EHPA, Cyanex272, and their mixture system in separation of some rare earth elements from a Nitric Acid solution
This work was aimed to evaluate and compare the performances of the solvents D2EHPA (Di-(2-ethylhexyl) phosphoric acid), Cyanex 272 (bis (2,4,4-trimethylpentyl) phosphinic acid), and a mixture system of D2EHPA and Cyanex272 in the separation of some rare earth elements (REEs) including lanthanum, gadolinium, neodymium, and dyspersym from a nitric acid solution. The results obtained showed that ...
متن کاملON THE COMPLEXING ABILITY OF ERIOCHROME BLACK T AS A METALLOCHROMIC INDICATOR FOR SOME ALKALI AND ALKALINE EARTH CATIONS IN ACETONE AND DIMETHYLSULPHOXIDE SOLUTIONS
The interaction between eriochrome black T and Li , Na , K ,Mg and Ca ions in acetone and dimethylsulphoxide solutions has been investigated spectrophotometrically. The formation constants of the resulting 1 : 1 complexes were determined and found to decrease in the order Mg >Ca >Li >K >Na in both solvents used. There is an inverse relationship between the stabilities of the complexes...
متن کاملSolvent Extraction and Transport of Rare Earth Metal Ions Using 5.11.17.23-Tetra-tert-butyl-25,27-bis (diethylcarbomoylmethoxy)-26,28-dihydroxy Calix[4]arene
The solvent extraction of rare earth metal ions from nitrate solutions by 5.11.17.23-tetra-tert-butyl-25,27-bis(diethylcarbamoylmethoxy)-26,28-dihydroxycalix[4]arene (L) in 1,2-dichloroethane has been investigated. The alalysis of the extraction equilibrium obtained from a mixture of La3+, Eu3+, Er3+ and Y3+ revealed that the extracted species hav...
متن کاملMeasures taken against water pollution in basic non-ferrous metal industries.
Waste water purification is shown to be an important field of environmental hygiene for non-ferrous metal industries. Hydrometallurgy becomes of greater importance for metal production and refining. Quality standards for drinking water and rivers require a minimum of some harmful impurities, e.g. metal compounds. The unit operations of hydrometallurgy technologically parallel the methods of eff...
