Abstract

The formation of polynuclear thorium hydroxide complexes in acidic aqueous solutions is observed by electrospray mass spectrometry. Size, number of hydroxide ligands and charge of all complexes in solution are identified independently. By repeated measurements over a time span of up to 418 days the stability of the polymers is observed. At concentrations above [Th(IV)] _tot = 10 mM pentamers and dimers are the dominant stable species. In contrast, the fractions of pentamers initially present at [Th(IV)]_tot = 0.2 mM decrease within less than 4 weeks, correlated with the formation of nm-sized colloids observed by LIBD indicating an Ostwald-ripening like process.
