Dependence of the electric field on the specific surface conductivity of PbO_2, 3PbO·PbSO_4 and 4PbO·PbSO_4

摘要

Our investigation is based on the relationship between the electric field and the surface conductivity of PbO_2, 3PbO·PbSO_4 and 4PbO·PbSO_4, and is evaluated at different temperatures and duration times. We used a suspension of each sample in a weak solution of H_2SO_4 (2.5 × 10~(-6) M) which has been titrated with a stronger acid solution of H_2SO_4 (1.58 × 10~(-3) M). The conductivity was measured during agitation, K-bar, and during sedimentation, K. When K-bar/K = 1, the iso-conductivity point under these specific conditions was analysed. The electrical field influenced the displacement of the particles in the solution.
