✦ Synopsis

Several d-block transition elements have been separated from mixtures by photochemical means, using lines from various lasers. The species involved, oxalato complexes of Fe and Co, eshibit selective photoreduction following absorption in bands in the visible and near ultraviolet regions of the spectrum. This experiment is apparently the fmt demonstration of selective laser photochemistry in liquid phase mixtures of chemically related elements.

Photochemical degradation of benzotriazole is investigated in aqueous solution at 25Β‘C and pH values varying in the range 3È11. The quantum yields at di †erent pH values are evaluated by analysing the kinetics of the reacting system. Reaction kinetics are markedly a †ected by pH because of its inΓ‘ue

The photochemistry of aqueous solutrons of iodide and bromide is investigated in the presence of high concentrations (2 x 10m2 M < C c 1.2 M) of nitrous oxide. In the iodide system, the photo-oxidation yfeids depend markedly on [N20]. The effect is attributed to the scavenging of solvated electrons
