Abstract
The present invention provides a method for quantitative determination of oxidant which method is capable of accurately and rapidly performing quantitative determination of oxidant at low cost, and an apparatus for quantitative determination of oxidant used in the method. The method for quantitative determination of oxidant according to the present invention is a method for quantitative determination of oxidant performing quantitative determination of oxidant in a sample using a redox reaction, the method including: adding one kind of reducing agent to a sample solution containing one or a plurality of kinds of oxidants having different lifetimes; producing an absorbance curve by measuring a time change in absorbance of the post-color-change or post-coloring reducing agent; and performing the quantitative determination of the oxidant while identifying the oxidant in the sample solution based on the obtained absorbance curve.
