    摘要: A iodine-measuring method for determining or detecting iodine concentration in a specimen, comprising a specimen-pretreating step of thermally digesting a specimen together with an oxidizing agent, and a subsequent reaction-measuring step of reacting the resultant with an arsenious acid reagent solution and an ammonium cerium sulfate reagent solution and measuring absorbance in the reaction solution, characterized in that the specimen-pretreating step is performed by heating and cooling treatment under an airtight condition.
