A review of recent literature focused on iodine determination/speciation in environmental, biological and clinical materials is provided. The review covers the different sample pre-treatments to extract total iodine, as well as specific iodinated forms, and the most used analytical techniques for assessing total iodine (cathodic stripping voltammetry, differential pulse voltammetry, neutron activation analysis, catalytic spectrophotometry, and atomic spectrometric techniques, mainly inductively coupled plasma-mass spectrometry) and iodine speciation (nonchromatographic methods, and mainly high performance liquid chromatography, gas chromatography and capillary electrophoresis coupled to electrochemical, UV spectrophotometric and mass spectrometric detection).
