STABILITY OF LYOPHOBIC COLLOIDS IN AQUEOUS MEDIA.

Abstract

Detachment and stabilization of solid contamination from weapon substrates presents a difficult problem in weapons cleaning. An understanding of the fundamental principles involved in the stabilization of solid contamination is, therefore, important for formulation of improved weapons cleaning materials. In this investigation, the stability of common weapon contamination was studied in aqueous surfactant solutions. Zeta potentials of aqueous dispersions of lyophobic colloids were determined by electrophoresis measurements and compared with sedimentation times of the dispersed systems. The stability of the dispersions was found to be governed by double-layer electrostatic repulsion at the surface of the colloidal particles. Calculations based on the Derjaguin-Landau-Verwey-Overbeek theory of stability were in excellent agreement with the experimental data. (Author)
