Manganese (Mn) - MBARI

Dissolved Mn can be determined by preconcentration of Mn 2+ using a chelating resin, such as Chelex-100, followed by graphite furnace atomic absorption spectrophotometry. It can also be determined by flow injection analysis with chemiluminescence or kinetic colorimetric detection (Chapin et a., 1990).
