Spectrofluorimetric determination of boron in soils, plants and natural waters with alizarin red S

A simple and sensitive spectrofluorimetric method for the determination of boron with Alizarin Red S is described. The fluorescence intensity of the complex formed in aqueous solution develops immediately and heating is not required. The excitation and emission wavelengths are 465 and 615 nm, respec...

Summary:A simple and sensitive spectrofluorimetric method for the determination of boron with Alizarin Red S is described. The fluorescence intensity of the complex formed in aqueous solution develops immediately and heating is not required. The excitation and emission wavelengths are 465 and 615 nm, respectively. The detection limit is 7.2 ng cm-3. A study was made of the influence of several ions as potential interferents. The method was applied satisfactorily to the determination of boron in soils, plants and natural waters.
