文摘The electrophoretic mobility of positively charged,cylindrically shaped α-FeO OH particles dispersed in dilute sodium chloride solutions was measured at 25℃,as a function of ionic strength and pH using microelectrophoresis apparatus. The mobility data were processed through a number of selected relationships that represent various stages of understanding of electrophoretic theory,culminating in the determination of values of the electrokinetic charge and zeta potential of the colloid α-FeO OH/NaCl aq.
