separation of americium and curium by use of tertiary pyridine resin in nitric acid methanol Mixed Solvent System
Journal of Radioanalytical and Nuclear Chemistry, 2007Co-Authors: Tatsuya Suzuki, K Otake, M Sato, Atsushi Ikeda, Masao Aida, Yasuhiko Fujii, M Hara, Toshiaki Mitsugashira, Masaki OzawaAbstract:The separation of Am and Cm by using the tertiary pyridine resin embedded in silica beads was studied in nitric acid/methanol Mixed Solvent System. This separation System of Am and Cm is very simple and easy. The adsorption and separation behaviors of Am and Cm were investigated with changing the nitric acid and the methanol concentrations. It was confirmed that Am can be almost completely separated from Cm.

effect of alcohols on elution chromatography of trivalent actinides and lanthanides using tertiary pyridine resin with hydrochloric acid alcohol Mixed Solvents
Journal of Chromatography A, 2004Co-Authors: Atsushi Ikeda, Tatsuya Suzuki, Masao Aida, Yasuhiko Fujii, M Hara, Toshiaki Mitsugashira, Masaki Ozawa, Keisuke ItohAbstract:Abstract Elution chromatography with a tertiary pyridine resin has been used to separate the trivalent actinides (An3+) from the lanthanides (Ln3+) using an alcoholic hydrochloric acid Solvent. Trivalent Am and Cm were separated from the Ln by employing a 1 cm (O)×10 cm resin column with the Mixed Solvent System composed of concentrated hydrochloric acid (HCl) and alcohols. The distribution coefficients (Kd) and the separation factors between An and Ln (αLnAn) increased as the alcohol content of the Solvent mixture increased. On the other hand, the Kd and αLnAn decreased drastically upon the addition of water to the Solvent mixture. Among the four alcohols investigated (methanol, ethanol, n-propanol and n-butanol), the ethanol–HCl Mixed Solvent System showed the largest Kd and αLnAn. The mechanism of adsorption for An and Ln cations on the pyridine resin is discussed in addition to the results presented herein.

determination and modeling of activity coefficients of cobalt chloride in the water ethanol Mixed Solvent System by potentiometric method at 298 15k
Journal of Molecular Liquids, 2014Co-Authors: Mohammad A. Bagherinia, Mohammad PournaghdiAbstract:Abstract In this work, the thermodynamic properties of (CoCl2 + C2H5OH + H2O) System were investigated by potentiometric method and based on Pitzer ion interaction model. For this purpose, primarily the mean activity coefficients of CoCl2 in pure water and ethanol–water mixture Solvent were determined using a galvanic cell without liquid junction potential of type: Co2 +-ISE|CoCl2 (m), C2H5OH (wt.%), H2O (100-wt.%) |Ag·AgCl. The measurements were performed at T = 298.15 K and at total ionic strengths from 0.001 to 6.000 mol·kg− 1 in various ethanol–water Mixed Solvent Systems containing 0, 10, 20, 30, 40 and 50% mass fractions of ethanol. The mean activity coefficients measured were correlated with Pitzer ion interaction model and the Pitzer adjustable parameters were determined. Then these parameters were used to calculate the thermodynamics properties for under investigated System. The results showed that the Pitzer ion interaction model can satisfactory describe the investigated System. The modified three-characteristic-parameter correlation (TCPC) model was applied to correlate the experimental activity coefficient data for under investigation electrolyte System, too. The results showed that the modified TCPC model also was suitable in the case of the Mixed Solvent System.

Journal of Molecular Liquids, 2000Co-Authors: J K Dash, M Sahu, M Chakrabortty, V ChakravorttyAbstract:Abstract An ultrasonic study has been made on solutions of lanthanum(III) chloride in water and in different proportion of (1%, 2.5%, 5% and 10%) maltose-water mixture at 303.15K to evaluate various acoustic parameters, viscosity, conductance and apparent molar volume. The results are discussed here in terms of ion-Solvent, ion-ion interaction and of structural effect on the Solvent in solution.

viscosity and acoustic behaviour of carbona to pentamine cobalt iii nitrate in water and glycerol water Mixed Solvent System
Journal of Molecular Liquids, 1997Co-Authors: P K Mishra, V ChakravorttyAbstract:Abstract The ultrasonic velocity and viscosity of carbonato pentamine Co (III) nitrate in water and different proportions of glycerol-water mixtures were determined at 303.15 K. The Jones-Dole viscosity B-coefficient of the coordination complex is found to be largest in 40% (v/v) glycerol-water mixture. Various acoustic parameters viz. isentropic compressibility, intermolecular freelength, acoustic impedance, etc. have been calculated using experimentally determined values of ultrasonic velocity and density. The variation of these acoustic parameters are discussed in the light of solute-Solvent and solute-solute interactions.
