Abstract

A flow injection technique for the determination of dissolved Mn in seawater and other natural waters has been developed. The technique utilizes the Mn-catalyzed oxidation of tiron by peroxide. The reaction product is determined colorimetrically. Sensitivity is enhanced and salt effects minimized through on-line preconcentration of Mn. For a 3-ml sample, a detection limit of 40 pmol kg-1 is possible. Use of a lab-built colorimetric detector can provide an inexpensive alternative to a commercial flow-through spectrophotometer.
