| Abstract: | The relevance of the work is associated with the need to accumulate data on electrokinetic stability of nanoparticles in solutions used in ecotoxicology. In this work the impact of electroexplosive nanopowder composition (Al, Ni, Zn), the composition of the dispersion medium (HEPES, surface water), and ultrasonic treatment on zeta-potential value was studied using dynamic light scattering technique. It has been shown that negatively charged particles (-16.7...-8.7 mV) changed their charge from negative to positive (11.1...20.5 mV) after ultrasonic treatment in surface water. In HEPES buffer solution the composition of the powder surface is of high importance: zeta-potential value was 26.3 - 20.6 - 0.4 mV for Al, Ni and Zn nanopowders, respectively. |
