Description
The complexation of uranium(VI) with silicate in the aqueous system was investigated using TRLFS as a function of pH, silicate concentration and temperature. Based on the recorded emission spectra a peak deconvolution was performed to obtain the free component spectra and calculate the complexation constant. To extract thermodynamic data and to compare the constant with estimation methods the experiment was also conducted at different temperatures.
