Popis:	The ζ-potential of lead sulfate has been studied by applying the streaming potential method to samples obtained by various preparative methods and subjected to various temperature treatments. All the ζ-potentials measured have a positive sign, irrespective of such conditions as the kind of reagents and excess ions used in the preparation or the pH value of the reacating solution. It has been postulated that the surface of lead sulfate is hydrolysed to produce lead hydroxide, whose ζ-potential is explicit in the measurement of the streaming potential of lead sulfate. This is supported by the pH value of the saturated solution of lead sulfate. The surface behavior of lead sulfate in relation to the dye adsorption can also be explained in this way.
