[Catalytic method of iodide ion determination in urine].

Kinetical catalytic method of iodide determination in urine was described. After wet ashing process in chloric/perchloric acid mixture kinetics of the trace iodide catalyzed reaction, cerium IV arsenic III was investigated. On the basis of nonlinear calibration curve determination of urine iodide in the range 0.1-5 microM/l was possible. High sensitivity range of iodide concentration and simplicity of performance predestinate described method for epidemiological studies in iodide deficiency regions.
