Abstract: | Abstract A simple post column reaction detection system for fluoride is presented using the decolorization of the zirconyl xylenol orange complex. A 3sgrave] detection limit of 0.05 μg F? mL?1 was achieved with a linear calibration function up to 10 μg F? mL?1. The methodology is suitable for the determination of F? in potable water and some interferences studies were conducted with common cations namely Ca, Mg, Al and Fe(III). |
