1H NMR and UV/Vis studies on the interaction of uranyl complex of salophene (bissalicylaldehyde- phenylenediimine) with nitrite, nitrate, sulphate, dihydrogenphosphate and fluoride anions are described. Only in the case of phosphate and fluoride ions an interaction was noticed. In the case of the former ion the changes in spectra were attributed to destruction of ionophore. The degradation of the ionophore is caused by the formation of uranyl phosphate, followed by hydrolysis of the Schiff base. Also the consecutive reaction might shift the hydrolysis equilibrium. NMRand UV/Vis studies aiming at the explanation of the mechanism of salophene decomposition are described.
