Abstract:
Values of a (coagulation efficiency) for coagulation of aluminum (hydr)oxide colloids by supramicron silica particles were generally near 0.01. Although the freshly suspended particles were oppositely charged, dissolved silica from the particulate silica adsorbs to the colloids reversing their charge. Bicarbonate also adsorbs and shifts the pHiep of the aluminum (hydr)oxide colloids. The addition of dissolved Al(III) had a similar effect on both types of particles. Dissolved silica adsorbs to the hydrous aluminum oxide surface and undergoes ligand exchange. This exchange can be simulated by a constant capacitance model for adsorption of aqueous species to the oxide surface and fits laboratory titration data.
