Sažetak
The effect of mercury (II), in the presence of iodide, on the fluorescence of the aqueous solution of rhodamine B was studied by means of the spectrofluorometric method. The optimum conditions in respect to the concentrations of mercury and iodide, the pH values and the effect of some salts on rhodamine B fluorescence quenching were determined. By the same method small amounts of mercury were measured in the waters from the Sava river. The results agree well with the values obtained by the method of atomic absorption spectroscopy.
