本文提出了一种用液体沉降天平法测量Zeta电位的新方法。使用的测试样品是球形丙烯酸和二氧化硅颗粒，并且使用珠磨机来增强颗粒分散。新方法可用于估计每个粒径范围的zeta电位。小颗粒的负zeta电位的绝对值大于大颗粒的负zeta电位的绝对值。用该方法测量Zeta电位的结果与其它常规测量装置的结果一致。随着珠磨机预处理过程之后的等待时间的增加，zeta电位相对于粒径的斜率减小。
A new method of zeta-potential measurement by the use of the liquid sedimentation balance method is developed. The test samples used were spherical acrylic and silica particles, and beads mill was used to enhance particle dispersion. The new method can be used to estimate the zeta-potential of each particle size range. The absolute value of the negative zeta-potential of small particles is greater than that of large particles. The results of measuring zeta-potential by the new method agree with other conventional measurement devices. The slope of the zeta-potential with respect to particle diameter decreases as the waiting period following the beads mill pre-treatment process increases.
