匕一oom一an dianwe一丫u dlandong dl占nwei表面电位与电动电位(surfaee potentials andeleetrokinetie Potentials)矿物界面双电层的两个重要的电性参数，表示矿物一水界面荷电的程度。浮选时矿物粒子在水溶液中要和各种离子发生作用，作用的结果经常使矿物表面的电性发生变化。故研究矿物表面的电性，即测定表面电位或电动电位的变化，可以找出矿物与浮选药剂作用的一些规律，进而分析矿物与药剂作用的机理。 表面电位是指固体表面与溶液内部的电位差，以申。表示。它主要取决于溶液中定位离子的浓度。表面电位与定位离子的活度之间的关系服从于能斯特方程，故表面电位的表达式为 RT，a+RT，a生 口n一.一二二In甲丁-一二丁In— n厂a千n厂a一式中R为气体常数;T为绝对温度;n为离子价数;F为法拉第常数;a+、a一为正、负定位离子的活度，在稀溶液中就等于它们的浓度;“年、a巴为表面电位为。时的正、负离子的活度。对于一些氧化矿物，H+和OH-离子是定位离子。当n一1，25C时上述表达式可以简化为必。=0.0591(pH。一pH)。式中pH。为表面电位为。时溶液的pH值，即为矿物的零电点。(见零电点与等电.点)可见，当溶液pH值大于矿物的零电点时矿物表面荷负电，反之荷正电。电动电位是指当溶液处在电场作用下，矿物粒子与溶液之间产生相对运动时，滑动界面上显示的电位，以夸表示。这一电位可用电泳法、电渗法、流动电位法或沉降电位法测出。使用得较多的方法是显微电泳法口对于一些氧化矿物，由于它不导电，理论研究上经常测定它的电动电位。 (龚焕高)
