Ion Chromatographic Study of Sulfate-Triethylenetetramine Complexes in Aqueous Solution.

Spectrophotometric Studies ot Vanadium(III) Ion Complexes th p-Sulfonatocalixf 41 acme In Aqueous Solution

Spectropholornetrie technique is used to evaluate binding of the vanadium(1U) ion to a water solublecaruc[4] arene molecule in aqueous solution. On the basis of the calculated value formation constant at25rC.we found that the eomplexation of this metal on is very favored towards 25, 26, 27, 2Stetrahydroxy-5, 11, 17, 23-tetnmulphonalic acid-calix[0]areneGaussian 03 package.

Uranium Removal from Aqueous Solution Using Ion-Exchange Resin DOWEX® 2x8 in the Presence of Sulfate Anions

The current study was attributed to uranium (VI) ions adsorption using a anion exchanger resin, Dowex®2x8, in the presence of sulfate anions. Evaluation of operational parameters including contact time, pH, initial concentration of uranium ions, and presence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution was assessed on sorption performance of ...

Thermodynamic study of Ion pairing in Aqueous solution of 〖BaF〗_2 by (_^19)F-NMR

The ion-pair association constant values, related to the reaction +  were determined by means of the NMR spectroscopy. The values of the thermodynamic functions of the ion pairing process were calculated on the basis of the NMR results. In addition, the association entropy was found to be dependent on the temperature. Comparing the experimental data and the Fuoss theory it is found that  ion-pa...
