Dissolution of Zinc Oxide Nanoparticles in the Presence of Slow Acid Generators

Abstract

We describe a preliminary investigation of the dissolution dynamics of zinc oxide nano-particles in the presence of cyclic esters (δ-gluconolactone and propanesultone) as slow acid gener-ators. The particles dissolution is monitored by means of turbidimetry and correlated with the evo-lution of pH over time. The results could be of interest for the design of chemically programmable colloidal systems.
