ملخص: Our investigation is based on the relationship between the electric field and the surface conductivity of PbO2,, 3PbO [middle dot] PbSO4 and 4PbO [middle dot] PbSO4,, and is evaluated at different temperatures and duration times. We used a suspension of each sample in a weak solution of H2SSO4 (2.5 x 106 M) which M) which has been titrated with a stronger acid solution of H2SSO4 (1.58 x 103 M). The c M). The conductivity was measured during agitation, t, and during sedimentation, K.. When K = = 1, the iso-conductivity point under these specific conditions was analysed. The electrical field influenced the displacement of the particles in the solution.
