摘　　要：采用pH电位滴定法测定了Cu(Ⅱ)—水杨酸配合物在离子强度为0.10mol.L-1(KNO3)条件下的pH值,用半整数作图法得出了Cu(Ⅱ)—水杨酸配合物的逐级稳定常数:lgk1=9.90,lgk2=7.32。The stability constants of complex of copper（Ⅱ） with salicylic acid have been determined by using the method of pH potential titration at ionic strength I = 0.10（KNO3）. The results indicate that the stability constants of complex of copper（Ⅱ） with salicylic acid are lgk1 = 9.90, lgk2 = 7.32.
