SummaryThe speciation of Eu(III) and Cm(III) was investigated by time resolved laser fluorescence spectroscopy (TRLFS) over a range of base concentrations from 0.01M NaOH to 7.5M NaOH and in the presence of several organic chelates including EDTA, HE

The development of an aqueous thermodynamic model for polymerized silica species is presented, which is valid for high ionic strengths and high dissolved silica concentration (∼0.1 m) at low temperature (22–25°C). The model is based on the Pitze

An aqueous thermodynamic model is proposed to describe the solubility ofTh(IV) hydrous oxide in the aqueous Na+-HCO3--CO32--OH--ClO4--H2O system extending to high concentration at 25‡C. This model is relatively simple in that only two aqueous speci
