WebFeb 1, 2014 · The present research defines the rates and structure of purified Mg-montmorillonite aggregates formed in the presence of monovalent (K +) and divalent (Ca 2+, Mg 2+) cations using light-extinction measurements. Time evolution of turbidity was employed to determine early-stage aggregation rates. WebJan 1, 1995 · It has been reported that these forces, which are polar but not electrostatic or electrodynamic, may have energies up to two orders of magnitude greater than those routinely calculated using the traditional DLVO theory (van Oss et al., 1988; van Oss, 1993). These polar forces derive from AB interactions between polar particles in polar media.
