DLVO THEORY Meaning and
Definition
-
DLVO Theory refers to the theoretical framework developed by Derjaguin, Landau, Verwey, and Overbeek for understanding the stability and interaction forces between colloidal particles in a liquid medium. It provides an explanation for the aggregation and dispersion behavior of particles in suspension, shedding light on the forces responsible for particle interactions.
According to the DLVO Theory, there are primarily two main forces that govern the behavior of colloidal particles: the Van der Waals forces and the electric double layer forces. Van der Waals forces are attractive forces that arise due to the fluctuating electrical dipoles present on the surface of particles, leading to an effective inter-particle attraction. Electric double layer forces, on the other hand, arise from the presence of ions in the medium surrounding colloidal particles. These ions form a diffuse layer around the particles, creating an electric repulsive force that counteracts the Van der Waals forces and serves to stabilize the suspension.
The DLVO Theory suggests that the stability of colloidal suspensions depends on the balance between these attractive and repulsive forces. When the repulsive forces dominate, particles repel each other and suspension remains stable. However, if the attractive forces become predominant, particles aggregate and form larger aggregates or flocs, resulting in suspension instability.
DLVO Theory has practical applications in various fields such as materials science, medicine, and environmental engineering. By understanding the forces influencing particle behavior, scientists and engineers can manipulate and control colloidal systems, impacting fields such as drug delivery, wastewater treatment, and fabrication of advanced materials.

Etymology of DLVO THEORY
The word "DLVO theory" is derived from the initials of the two scientists who developed it, as well as the type of forces it describes. The "DL" represents Derjaguin and Landau, while the "VO" represents Verwey and Overbeek. The DLVO theory, also known as the DLVO (Derjaguin-Landau-Verwey-Overbeek) theory, explains the stability and interaction between colloidal particles in a liquid medium. This theory combines concepts from intermolecular physics and electrochemistry to explain the forces between charged particles in solutions.
