Urinary iodine assays and ionophore based potentiometric iodide sensors

Abstract: Urinary Iodine has been widely regarded as a biochemical marker for control of iodine deficiency disorders. Based on the Sandell-Kolthoff reaction, most colorimetric assay methods for urinary iodine (UI) determination that have been developed require pretreatment of urine sample. The non-Sandell-Kolthoff methods for UI assay provide alternative approaches for UI assay requiring only simple pretreatment or even without pretreatment. The selective ionophore-based iodide electrodes are highly applicable to the UI… Show more

“…Different methods were used to determine levels of bromide, respective iodine ions in milk and other food products, drinking water and urine [ 32 , 33 ] Thus, kinetic colorimetric ceric-arsenic assay [ 34 ] gas chromatography (GC) and ion chromatography (IC) [ 35 ], high performance liquid chromatography (HPLC) [ 36 ], mass spectrometry (MS) [ 37 ], inductively coupled plasma mass spectrometry (ICP-MS) [ 38 ] were used. The GC method showed higher accuracy compared to the IC procedure and provided a detection limit of 0.4 mg/L when evaluating the levels of bromide ion in urine samples of workers exposed to methyl bromide [ 35 ].…”

“…Similarly, biochemical measurements for iodine and thyroid function tests must be standardized if epidemiological studies are to be compared. The current focus is on ensuring that urinary iodine measurements are standardized (5).…”

“…In recent years, much effort has been devoted to synthesizing iodide-selective ionophores that have greater selectivity than silver salt-based Ises; these efforts were covered in a review [23]. electrochemical detection in general and amperometric detection in particular are popular for iodine determination because of the fast response time and sensitivity for the analyte of interest.…”
