Stability of Colloidal Bentonite Particles in Aqueous Systems
Original language description
The objective of this study was to investigate the stability of bentonite colloids during the interaction of bentonite with water under different conditions. Classical sedimentation tests are an easy method for studying the colloidal stability. There were studied the effect of bentonite saturation time, the concentration of electrolyte (NaCl) and type of the electrolyte (KCl and MgCl2) on the stability of colloidal particles. It was found that sedimentation of colloidal particles occurs in three phases.The most significant point on the all curves is the beginning of the second phase, which corresponds to the rapidly increasing amount of sedimented particles. For this reason, the effect of different conditions on the stability of particles is the mostevident at this point. It is the phase of the intensive sedimentation. Stability of bentonite colloids decreases with increasing concentration of electrolyte and saturation time.
