摘　　要：研究了固体浓度对方解石动电行为的影响。结果表明，方解石ｚｅｔａ电位在不同的固体浓度下有很大的差别，低固体浓度下方解石荷负电，高固体浓度下荷正电。低固体浓度下，随搅拌时间的延长，方解石的ｚｅｔａ电位也由正变负。对方解石ｚｅｔａ电位变化的机理进行了初步探讨。The effect of solid concentrations on the electrokinetic behavior of calcite was studied. The results showed the zeta potential of calcite is heavily dependent on solid concentration. The zeta potential of calcite is negative at low solid concentrations and positive at high solid concentrations. At the same time the zeta potential is dependent on conditioning time. At low solid concentrations, the zeta potential of calcite also changed from positive to negative with the increase of conditioning time. The phemomena was discussed in this paper.
