Use of a periodate-sensitive perchlorate ion-selective electrode in the kinetic ultramicrodetermination of manganese(II) by means of its catalytic effect on the periodate-acetylacetone reaction.
A kinetic method for the ultramicrodetermination of maganese, based on its catalytic effect on the periodate-acetylacetone reaction, is described. A perchlorate electrode is used as a periodate sensor to monitor the reaction. The time required for the potential to change by a preselected amount (10 mv) is measured automatically and related directly to the manganese concentration. Amounts of manganese in the range 40-240 ng were determined with relative errors of about 2-4%.
