摘　　要：The effects of petroleum sulphonate, HPAM and pH value on the zeta potential of Na-montmo-（rrillonite） suspensions were investigated, and orthogonal design of experiment was used to study the effect of these factors on the zeta potential of montmorillonite suspensions when the three factors existed simultaneously. The results show that the zeta potential of montmorillonite becomes more negative with the increase of the concentration of petroleum sulphonate, that of HPAM, and the pH value. Moreover, FpH=13.3(>F0.01=9.78), FHPAM=7.73(>F0.05=4.76) and Fpetroleum sulfonate=3.05 when the three factors co-exist, thus the effect of pH value on the zeta potential of montmorillonite is the most prominent factor, the HPAM a less prominent factor, and the petroleum sulphonate is least prominent.The effects of petroleum sulphonate, HPAM and pH value on the zeta potential of Na-montmorrillonite suspensions were investigated, and orthogonal design of experiment was used to study the effect of these factors on the zeta potential of montmorillonite suspensions when the three factors existed simultaneously.
