“…In order to determine the bromine and the iodine in such samples, sensitive analytical methods are required. Neutron activation analysis6–10 and X‐ray fluorescence spectrometry11 methods have been reported for the total analysis of halogens, and chromatographic methods such as ion chromatography with conductivity detection,12 ion chromatography with UV detection13 and capillary electrophoresis with UV detection14 have been employed for speciation studies. If its use is restricted to iodine detection, luminol chemiluminescence can be employed 15…”

A procedure for the simultaneous determination of bromine and iodine by inductively coupled plasma (ICP) mass spectrometry was investigated. In order to prevent the decrease in the ionization efficiencies of bromine and iodine atoms caused by the introduction of water mist, electrothermal vaporization was used for sample introduction into the ICP mass spectrometer. To prevent loss of analytes during the drying process, a small amount of tetramethylammonium hydroxide solution was placed as a chemical modifier into the tungsten boat furnace. After evaporation of the solvent, the analytes instantly vaporized and were then introduced into the ICP ion source to detect the (79)Br(+), (81)Br(+), and (127)I(+) ions. By using this system, detection limits of 0.77 pg and 0.086 pg were achieved for bromine and iodine, respectively. These values correspond to 8.1 pg mL(-1) and 0.91 pg mL(-1) of the aqueous bromide and iodide ion concentrations, respectively, for a sampling volume of 95 microL. The relative standard deviations for eight replicate measurements were 2.2% and 2.8% for 20 pg of bromine and 2 pg of iodine, respectively. Approximately 25 batches were vaporizable per hour. The method was successfully applied to the analysis of various certified reference materials and practical situations as biological and aqueous samples. There is further potential for the simultaneous determination of fluorine and chlorine.

“…The amount of fluoride released from organic compounds and present initially in the sample as organic fluorine can be determined using different methods. Potentiometry with the fluoride ion-selective electrode and ion-chromatography are most frequently used for this purpose, but indirect spectrophotometric methods in the UV/VIS range, methods that require more complex instrumentation such as NMR, 25 X-ray fluorescence spectroscopy, 28 neutron activation analysis, 29 or ICP-MS 30 have also been used. One of the established methods for determination of total fluorine at trace levels involves combustion of a sample in an oxygen/hydrogen flame (Wickblod decomposition), absorption of the resulting fluoride in water and potentiometric detection of fluoride with the fluoride ion-selective electrode.…”

Since the perfluorinated organic compounds have been recognized as persistent organic pollutants present in the environment, food and living organisms, new analytical methods are being developed for their determination. Many of the described earlier methods focus on determination of particular fluorinated compounds, however, the specific compounds are only a part of all organic fluorine compounds present in environmental or biological samples.
