Effects of inorganic cations and organic polymers on the physicochemical properties and microfabrics of kaolinite suspensions

摘要: Abstract The effects of inorganic cations and organic polymers on the physicochemical properties microfabrics which including floc size distributions kaolinite suspensions were systematically investigated by batch sedimentation tests. Kaolinite surface charges, salt concentrations polymer polarity as well dosage found to be key factors that affect particle associations, sizes, zeta potential, turbidity a suspension. relationship between flocs turbidity, potential sediments established significance understanding induced flocculation aggregation suspended was discussed. Assisted measurements, an increase ionic strength compress electrical double layer (EDL) result in imbalance interparticle forces, thus associations sizes varied significantly. addition facilitate through long-range bridging short-range ion-dipole interaction, hydrogen bonding Colombian interactions, turn affected size, suspensions. Test results also showed clay-polymer possessed unimodal lognormal distribution (PSD) leading more quantitative sediments.
