At the Institute of Resource Ecology, the complexation of Eu(III) and Cm(III) with aqueous phosphate was studied using laser-induced luminescence spectroscopy at low pH ([H+] = 0.1 M), different ionic strengths (0.6 to 3.1 M) and different temperatures (25 to 80 °C). The data set contains the species distribution, slope analysis and the extrapolation to zero ionic strength using R.
