Descripción
A simple flow injection fluorimetric method for fluoride determination is proposed. The method is based on the enhanced fluorescence of quercitin-Zr(IV) complex when fluoride ion is present in the sample. An open/closed FIA manifold with a mini-column of Dowex 50W X8 resin was used to remove the most important interference (aluminum). The two FIA assemblies were integrated on-line to automate the pretreatment of the water sample and fluoride determination. The calibration graph was linear over the range 0.1-3.0 μg ml-1 of fluoride with a correlation coefficient of 0.999 and LOD 0.06 μg ml-1. The relative standard deviation was 2.5% and the sample throughput was 52 h-1 without pretreatment and 10 h-1 with pretreatment of the sample. The method was applied to the determination of fluoride in water samples.
