摘要: Abstract The stability ratios of suspensions α-alumina in aqueous solutions sodium dodecyl sulfonate at constant ionic strength were determined pH 6.9 and 7.2 25°C. 45°C, by measuring the rate change turbidity. Measurements adsorption surfactant alumina electrophoretic mobilities particles extent coagulation same system gave isotherms general form. This indicates that this results mainly reduction diffuse layer potential because adsorption. dependence on is extremely marked; there a much lesser temperature. Stability also calculated from mobility data, variation with concentration was compared evaluated turbidity measurements.
