【摘要】用北京同步辐射(BSRF)研究了Cs2SO4溶液298 K的水合结构。研究结果表明,溶液中占优势的物种是六水合铯离子和八水合硫酸根离子,揭示了硫酸铯溶液结构,并讨论了浓度对水合结构的影响。硫酸铯溶液中没有发现离子对的存在。更多还原

【Abstract】 The hydration structure of Cs₂SO₄ solutions has been investigated by synchrotron radiation with the Beijing Synchrotron Radiation Facility（BSRF） at 298 K.Calculations of the structural model shows that the dominant species in the solutions are hexaaquo-cesium and octaaquo-sulfate ions and the hydration structure of the aqueous solutions of cesium sulfate has been revealed.Effects of concentration on the hydration structure of the ions are also discussed.In addition,no ion pairs have been found in such solutions.更多还原
