Abstract
An automatic spectrophotometric reaction-rate method is described for the ultramicrodetermination of manganese(II). The method is based on the potassium periodate-diethylaniline reaction which is catalyzed by manganese. The time required for the reaction to produce a small fixed amount of colored product is measured automatically and related directly to the manganese concentration. Maximum tolerable amounts of interfering ions were determined. Ultramicro amounts of manganese in the range 3-30 ng were determined with relative errors of about 2% and measurement times of 15-150 seconds. The coefficient of variation was 1.0%. The method was applied for the determination of manganese in natural waters. © 1969 Springer-Verlag
