The use of zirconyl xylenol orange for the post-column spectroscopic detection of fluoride in ion chromatrography

A simple post column reaction detection system for fluoride is presented using the decolorization of the zircouyl xylenol orange complex. A 3σ 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, A1 and Fe(III). © 1993, Taylor & Francis Group, LLC.
