Specific and Selective Determination Method for Halide Anions by a Flow Injection Technique

A flow-injection analysis system is described for the determination of halide (chloride, bromide and iodide) anions. This method could be used as a post column detection method for these anions in water samples. The system is based on the specific and selective reaction between halide anion and fluo...

Summary:A flow-injection analysis system is described for the determination of halide (chloride, bromide and iodide) anions. This method could be used as a post column detection method for these anions in water samples. The system is based on the specific and selective reaction between halide anion and fluorescein with an oxidant in an acidic flow. The product is detected at 530 nm in an alkaline flow. The detection limits of the three anions under the conditions tentatively established for the determination of bromide anion were as follows ; Cl-, 1×10-8mol ; Br-, 1×10-10mol ; I-, 1×10-10mol.
