英文摘要	The solubility of sodium tungstate dihydrate and sodium molybdate dihydrate in the (Na2MoO4 + Na2WO4 + Na2SO4 + H2O) system was studied using experimental and calculated methods. The osmotic coefficient of sodium tungstate was fitted to calculate the thermodynamics parameters of (Na2WO4 + H2O) system. The solubility of sodium tungstate dihydrate was determined using the dynamic method in Na2WO4-Na2SO4-H2O to establish the new model which can provide an estimate the solubility of sodium tungstate dihydrate in various conditions, combined with the data published, the solubility of sodium tungstate dihydrate and the sodium molybdate dihydrate in quaternary system of (Na2MoO4 + Na2WO4 + Na2SO4 + H2O) was estimated using the parameters of the two ternary systems of (Na2WO4 + Na2SO4 + H2O) and (Na2MoO4 + Na2SO4 + H2O). The results show that the AARD is always small and the calculated value is basically consistent with the experimental values for the system studied. (C) 2016 Published by Elsevier Ltd.
