采用热力学离子交换平衡的实验方法测试了Ｋ型白庙子斜发沸石上２Ｋ＋（ｚ）Ｃｕ２＋（ｓ）交换体系在不同温度、不同Ｃｕ２＋初始浓度时的Ｃｕ２＋平衡交换量Ｑ∞、交换效率η、离子校正选择商Ｋｃ、分离系数α以及△ｒＧｍ、△ｒＨｍ、△ｒＳｍ等热力学数据．实验结果表明，该矿样上Ｑ∞、η、Ｋｃ、α等均受交换温度和溶液Ｃｕ２＋初始浓度的影响．其中，浓度的影响与电解质溶液的熵效应、溶液的非理想程度均有关．并且，随着交换实验条件的改变，该矿样对Ｃｕ２＋、Ｋ＋离子的热力学亲合力也有改变 The balance of Cu2 + exchange rate Q∞ and exchange efficiency η at different temperatures and initial concentrations of Cu2 + were investigated by thermodynamic ion exchange equilibrium method. Ion correction selection quotient Kc, separation coefficient α and △ rGm, △ rHm, △ rSm and other thermodynamic data. The experimental results show that Q ∞, η, Kc, α and so on are all affected by the exchange temperature and initial Cu2 + concentration. Among them, the influence of the concentration is related to the entropy effect of the electrolyte solution and the non-ideal degree of the solution. And, with the exchange of experimental conditions change, the ore samples of Cu2 +, K + ion thermodynamic affinity also changed
