Solubility data for the quaternary system (Li₂SO₄ + Na₂SO₄ + MgSO₄ + H₂O) is very important for the separation of lithium sulfate from the salt lake brines in Qaidam Basin. The experimental and calculated solubilities of the quaternary system (Li₂SO₄ + Na₂SO₄ + MgSO₄ + H₂O) at T = 288.15 K and P = 0.1 MPa were determined. It is shown the solid phases Li₂SO₄·H₂O, Na₂SO₄·10H₂O, and MgSO₄·7H₂O and a new complex salt Li₂SO₄·3Na₂SO₄·12H₂O exist in this system. The solubilities of this quaternary system were predicted using the Harvie–Møller–Weare (HMW) model of electrolyte ion-interaction theory. The modeling solubility isotherms agree well with experimental data, which indicates the solubilities and model parameters obtained in this work are reliable.

288.15 K时四元体系（Li ₂ SO ₄ + Na ₂ SO ₄ + MgSO ₄ + H ₂ O）的固液相平衡：实验和模型模拟

四元系统的溶解度数据（Li ₂ SO ₄ + Na ₂ SO ₄ + MgSO ₄ + H ₂ O）对于从柴达木盆地盐湖盐水中分离硫酸锂非常重要。确定了在T = 288.15 K和P = 0.1 MPa时四元体系（Li ₂ SO ₄ + Na ₂ SO ₄ + MgSO ₄ + H ₂ O）的实验和计算溶解度。示出了固相Li ₂ SO ₄ ·H ₂ O，Na ₂ SO₄ ·10H ₂ O，并用MgSO ₄ ·7H ₂ O和新的配盐栗₂ SO ₄ ·3NA ₂ SO ₄ ·12H ₂ ö在该系统中存在。使用电解质离子相互作用理论的Harvie-Møller-Weare（HMW）模型预测了该四元体系的溶解度。建模的溶解度等温线与实验数据吻合良好，表明在这项工作中获得的溶解度和模型参数是可靠的。
