Abstract
In alkaline solution (1 hi NaOH) irradiation (lambda(ir) = 266 nm) of both TlOH and Sn(OH)(3)(-) leads to the formation of hydrated electron and oxidi zed complex in the primary photochemical step. In both cases nascent hydrat ed electrons react with the ground-state hydroxometalates to form the corre sponding reduced compounds. The main reaction of these latter species is re combination (synproportionation) with the oxidized complexes, significantly diminishing the efficiency of the overall light-induced oxidation of TlOH and Sn(OH)(3)(-).
