Dlvo-type interactions
The DLVO theory (named after Boris Derjaguin and Lev Landau, Evert Verwey and Theodoor Overbeek) explains the aggregation and kinetic stability of aqueous dispersions quantitatively and describes the force between charged surfaces interacting through a liquid medium. It combines the effects of … See more DLVO theory is a theory of colloidal dispersion stability in which zeta potential is used to explain that as two particles approach one another their ionic atmospheres begin to overlap and a repulsion force is … See more The DLVO theory of colloidal stability has been extended to take into account the effect of shear flow in fluid dynamic systems, which is relevant for many applications e.g. See more Additional forces beyond the DLVO construct have been reported to also play a major role in determining colloid stability. DLVO theory is not effective in describing ordering processes such as the evolution of colloidal crystals in dilute dispersions with low salt … See more In 1923, Debye and Hückel reported the first successful theory for the distribution of charges in ionic solutions. The framework of linearized Debye–Hückel theory subsequently was … See more DLVO theory is the combined effect of van der Waals and double layer force. For the derivation, different conditions must be taken into account and different equations can be obtained. … See more Since the 1940s, the DLVO theory has been used to explain phenomena found in colloidal science, adsorption and many other fields. Due to the more recent popularity of nanoparticle research, DLVO theory has become even more popular because it can be … See more WebFor the non-DLVO type surface interactions, such as steric and bridge forces originating from the surfactant adsorption and other surface modifications in organic solvents, a colloid probe atomic force microscopy (CP-AFM) is a useful method to …

Previous studies show that colloidal suspension of clay minerals and iron oxides that also contain abundant organic matter (OM), especially humic acid (HA), resists aggregation under increased electrolyte concentrations [ 26 – 31 ]. garth guthrieWeb(DLVO) theory. This model is based on the balance be-tween van der Waals attraction and electrostatic repulsion [1,2]. While appropriate for a wide variety of systems, the DLVO approach failed to account for some experimentally observed features of stability behavior. Hence, other types of interactions have been put forth [3].
