Improved theoretical calculation of the stability ratio for colloidal systems

Colloidal Stability of Polymer Colloids with Variable Surface Charge

“…Going back to the stability factor, W, it was redefined by McGown (21), taking into consideration the fact that when in rapid coagulation, the attractive contribution to the interaction potential still acts. Thus, the new expression for W is…”

Fractal Structures and Mechanisms in Coagulation/Flocculation Processes in Environmental Systems: Theoretical Aspects

“…The Derjarguin, Landau, Verwey, Overbeck (DLVO) theory [23][24][25] has established the potential energy-distance relationship between two particles as a function of the characteristics of both the particles and the suspending solution. In natural systems, this approach requires compilation [26][27][28] of the major key physicochemical parameters that characterize the colloid material, including: (a) colloid shapes The combination of van der Waals and electrostatic forces usually results in two minima (primary and secondary minima) where aggregates are more or less stable.…”

Coagulation in a shear field generated by stirring in a cylindrical vessel

“…Extending the definition of the stability ratio for the case of perikinetic coagulation (19,20) to orthokinetic coagulation, we used (coagulation rate including all interactions except electrocratic repulsion) W = [6] (coagulation rate including all interactions)…”
