Abstract
Iodine concentration in urine is the direct quantity indicator of the current consumption of iodine in the population. The most widespread method of determination of iodine in urine is cerium-arsenic method with preliminary processing samples of urine using the solution ammonium persulfate. The purpose of work was to develop updating of the given method for reduction of the formation of toxic products of the reaction. Described method has good characteristics (the limit of the detection of this method 11 ug/l, CV < 10 %, the coefficient of the correlation with reference method 0.99), the amount of toxic substances formed during reaction decreases in 3 times, the cost price of research is reduced owing to reduction of the volume of reagents and water.
