Abstract

PURPOSE:To obtain a higher measuring accuracy, by arranging a means of dissolving an analysis sample and a means of determining the amount of a reducing agent by a coulometric titration method in a closed container which is filled with an electrolytic solution containing a reducing agent to cut oxygen in the air. CONSTITUTION:About 30mg of an analysis sample is placed into a preliminary chamber and a liquid drain cock 21 is opened to inject a specified amount of a reducing agent solution in a burette into a main cell chamber 1. A partition 7 is opened with a push bar 9 to put a sample into the main chamber. After the sample is dissolved stirring up the solution with a rotator 22, a DC power supply with a coulometer is connected between an electrode 2 for titration and an opposed pole 18 to run the DC. Here, with a reaction in the titration electrode, Cu<+> as reducing agent is oxidized to be Cu<2+>. Therefore, when a potential of an indication electrode is measured with respect to a reference electrode simultaneously with the titration, the potential rises with the reaction and then, as the Cu<+> is almost consumed, the potential rises steeply. Thus, at this point, the end of the titration can be judged.
