| Popis: | This study was aimed at further examining of a detonated nanodiamond hydrosol, produced by the NanoCarbon Research Institute, Japan. In the concentrated solution, this colloidal system consists mainly of 3 nm-sized primary particles. These particles are positively charged and tend to associate into larger colloidal species on dilution. The species adsorb, first of all, the anionic dyes and readily coagulate on adding electrolytes. Some properties of the sol are changed during prolonged ageing but may be restored by adding small HCl amounts. Besides measuring the electrokinetic potential, the interfacial electrical potential was estimated by using acid-base indicators. |
