Characterization of particles of the dispersed system based on low-concentrated aqueous solutions of L-cysteine and silver acetate

Abstract

Abstract The authors of this work conducting a study of the precursor of reference materials of the zeta potential of particles in dispersed systems. The precursor is based on supramolecular solution of L-cysteine and silver acetate (CSSac). Particles and aggregates of CSSac were studied by dynamic light scattering (DLS), phase analysis of scattered radiation (PALS), inductively coupled plasma mass spectrometry (ICP-MS) and high-resolution transmission electron microscopy (HR-TEM). It was established that the diameter of the potential-determining aggregates of the CSSac is in the range from 20 nm to 100 nm. These aggregates consist of nanoparticles up to 10 nm in diameter.
