To inves.igate the interactions.of op.os.tely charged s.tes.on the s.rfaces.of variable-charge s.il p.rticles.with cations.and anions. and to evaluate the mean Gibbs.free binding and ads.rp.ion energies.of various.cations.on p.rticles.of red s.il and latos.l, clay fractions.s.aller than 2 μm were s.p.rated from s.mp.es.of the two variable-charge s.ils. Ferric oxides.were removed from p.rt of the clay fractions. which were then s.turated with various.chlorides.（NaC1, KCl, CaCl2, CdCl2 or LaCl3）. Electrical conductivities.（EC） of dilute s.s.ens.ons.of the original and of the iron oxides.free clay fractions.in deionized water were meas.red with the s.p.2 s.ort high-voltage p.ls. ap.aratus. which enables.meas.rement of the Wien effect at field s.rengths.（E） from 14 to 250 kV cm^-1. The Wien effect （EC-E） curves.revealed EC increas.s.of red s.il s.s.ens.ons.between 14 and 200 kV cm^-1, of 8.3, 8.4, 12.1, 5.9, and 1.2 μs.cm^-1 for NaCl, KCl, CaCl2, CdCl2, and LaCl3, res.ectively, reflecting the differing interactions.with the various.cations.and chloride. The EC increments.with the iron-free red s.il s.s.ens.ons.were higher, being 29.7, 17.2, and 15.3 μs.cm^-1 for NaCl, CaCl2, and CdCl2, res.ectively. In the natural latos.l s.s.ens.ons.the EC increments.were p.actically zero, whereas.in the iron-free fractions.there were s.gnificant EC increments.of 10.3, 5.7, 5.0, and 1.6μs.cm^-1 for NaCl, CaCl2, CdCl2, and LaCl3, res.ectively.
