Spectrofluorimetric determination of zinc in foods with 8-(p-toluenesulphonamido)quinoline in micellar medium.
A new method for the spectrofluorimetric determination of zinc with 8-(p-toluene- sulphonamido)quinoline in a Brij-35 micellar medium has been developed. This method allows the determination of 8-550 ng/ml Zn(II) and is relatively free from interferences. It has been applied to food samples with satisfactory results.
