Abstract. The results of the development of a domestic zeta potential reference material for liquids, designated MDP-P90, based on an amino acid-stabilized silver nanoparticle sol, are presented. Studies were conducted to obtain a stable sample of the dispersed system with a reproducible zeta potential value. As a result of the research, a zeta potential reference material for particles in liquid was developed, with a zeta potential value of plus 90 mV (MDP-P90). The relative error in reproducing the zeta potential (mean zeta potential value) does not exceed ± 8 %.
