High Energy Chem. (Engl. Transl.) 9: 493-4 (1975)

UO22+ quenched by UO2+ at conc. <= 2.7 x 10–4 mol L–1
Solvent : H2O, 0.4 mol/L HClO4; 2 mol/L LiClO4, 14ºC

kq = 5 x 109(L mol–1 s–1)


Experimental methods: steady state irradiation, luminescence
Lifetime in the absence of quencher, air free = 1.3 micro sec. (747132)
Comments: Q formed in situ by the red'n of S with Eu2+, see Mech. [4]
