Impact of Al³⁺ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior. [PDF]

ChemistryOpen
The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...
