Determination and Correlation of Solubility of Yttrium Oxalate in Oxalic Acid Solution AITranslate
Abstract AITranslate
The solubility of yttrium oxalate in oxalic acid solution with different concentration(0.6~1.0 mol/L) was determined by FBRM combined with dynamic method at atmospheric pressure and 318.15~343.15 K.The experimental results show that the solubility of yttrium oxalate in oxalic acid solution with different concentration decreases with the increase of temperature and increases with the increase of oxalic acid concentration.Apelblat equation and polynomial empirical equation are used to fit and correlate the experimental data, and the correlation results are good.When the concentration of oxalic acid is low, the effects of the two models are similar.When the concentration of oxalic acid is high, Apelblat equation is slightly better than polynomial empirical equation.The solution enthalpy and entropy of yttrium oxalate in different oxalic acid solution calculated by Van′t Hoff equation are negative, the dissolution process is a non-spontaneous exothermic process, and the main driving force of this process is entropy driving.
