Simultaneous determination of fluoride and phenolics in water using flow-injection analysis

Abstract

The design, development, and testing of a flow-injection analysis (FIA) manifold for the simultaneous determination of two species in water samples are reported. Fluoride is determined potentiometrically, and, following on-line sample dilution and treatment, amperometric analysis of phenolics is performed. The combination FIA system is a rapid, low-cost, highly reproducible method that uses small sample volumes and could be used to provide on-site near-real-time measurements. © 1999 John Wiley & Sons, Inc.
