Effect of Interaction Between Clay Particles and Fe3+ Ions on Colloidal Properties of Kaolinite Suspensions
Colloid Electron Microscopy Flocculation Iron Kaolinite Sedimentation Zeta Potential
font style='font-size:12px;'>
2011/12/22
Abstract: Fine kaolinite suspensions were mixed with unaged or aged FeCl3 in this experiment. The interaction between clay particles and Fe3+ hydrolysis products was studied by transmission electron m...

2011/12/1
Abstract: Currently, two commercial plants, operating in the Athabasca region of Alberta, produce approximately 20 percent of Canada's petroleum requirements from oil sands. Surface mined oil sand is ...
Size and Shape of Allophane Particles in Dispersed Aqueous Systems
Allophane Cluster Colloid Domain Light Scattering Shape Size Ultrafiltration Viscosity
font style='font-size:12px;'>
2011/12/27
Abstract: Aqueous suspensions of allophane show relatively high viscosity, presumably because of strong particle interaction between the unit particles. To test this hypothesis, we measured the partic...
Separation of Sub-Micron Particles from Soils and Sediments without Mechanical Disturbance
Clays Dialysis Dispersion Mobility Particles Sediments Separation Size Soils Submicron Swelling
font style='font-size:12px;'>
2011/12/1
Abstract: A method is described for the separation of the finest particles from soils and sediments without mechanical disturbance. Particles are separated through the induction of osmotic stress. Gen...
