Time-resolved laser fluorescence spectroscopy TRLFS

Stumpf, Th. Fanghanel, Th. 2002. A time-resolved laser fluorescence spectroscopy (TRLFS) study of the interaction of trivalent actinides (Cm(III)) with calcite. Journal of Colloid and Interface Science, 249, 119-122. [Pg.543]

Recently, Wimmer et al, (20) used time-resolved laser fluorescence spectroscopy (TRLFS) to reinvestigate the hydrolysis reaction of Cm in 0.1 M... [Pg.363]

Conventional optical absorption spectrometry has detection limits of between 0.01 and 1 mM for the actinides. Highly sensitive spectroscopic methods have been developed, based on powerful laser light sources. Time resolved laser fluorescence spectroscopy (TRLFS), based on the combined measurement of relaxation time and fluorescence wavelength, is capable of speciating Cm(III) down to 10 mol/L but is restricted to fluorescent species like U(VI) and Cm(III). Spectroscopic methods based on the detection of nonradiative relaxation are the laser-induced photoacoustic spectroscopy (LPAS) and the laser-induced thermal leasing spectroscopy (LTLS). Like conventional absorption spectroscopic methods, these newly developed methods are capable of characterizing oxidation and complexation states of actinide ions but with higher sensitivity. [Pg.19]

A detailed study of the hydrolysis reactions of curium(III) has been undertaken by Fanghanel et al. (1994) in NaCl media and at 25 "C using time-resolved laser fluorescence spectroscopy (TRLFS). This study provided data on the stabihty constants of CmOH + and Cm(OH)2 in 0.011-6.15molkg NaCl. The constants relate to reaction (2.7) (M = Cm ", p=, q= oi2). The reported stabihty constants are listed in Table 9.26 and are given with respect to reaction (2.7). [Pg.419]
