Abstract
The formaldoxime colorimetric method for manganese, previously utilized for freshwater and seawater samples of large volume, has been modified for the analysis of small volume, iron-rich sediment pore water samples. Using as little as 3 ml of sample and the addition of EDTA to destroy the Fe-formaldoxime interference (at concentrations of 9 μM Mnl−1), a precision of 3% is obtained.Keywords
