Direct imaging of aggregates in aqueous clay-suspensions by x-ray microscopy
The applicability of x-ray microscopy for the direct investigation of clay aggregates in water is demonstrated. As coagulating agents Ca2+, an anionic and a cationic detergent were used. The internal structures of the aggregates formed by the addition of the surfactant could be clearly visualized.
