dissolution and stabilization have been previously studied in vitro using acidicaqueousenvironments. Nanoceria agglomerated in the presence of some carboxylic acids over 30 weeks, and degraded in others, at pH 4.5 (i.e., the pH value in phagolysosomes). Plants release carboxylic acids, and cerium
a second carboxylic acid group may optimally complex with nanoceria. The results provide mechanistic insight into the role of carboxylic acids in nanoceria dissolution and its fate in soils, plants, and biological systems.
Keywords: acidicaqueousenvironments; carboxylic acids; electron microscopy
was to test whether carboxylic acids stabilize or accelerate nanoceria dissolution in acidicaqueousenvironments and determine the mechanism of dissolution depending on the molecular structure of each ligand relating to agglomeration or stabilization. In addition, the influence of ambient laboratory
