Abstract: Colloidal stability is one of the critical factors for the use of nanodiamonds as potential enterosorbents. Although nanodiamonds are believed to be a promising enterosorbent, colloidal stability in hydrosols of raw polydispersed nanodiamonds produced by detonation is typically low. Surface modification and fractionation significantly improves colloidal stability of nanodiamond suspensions within the physiological pH range. The modification of nanodiamonds can be completed either by physical means, i.e., plasma treatments, or by chemical methods. In the current paper an analysis of the colloidal stability of detonation nanodiamonds hydrosols, which have undergone different surface modifications, is presented based on zeta potential measurements and titration experiments.
