A method for the determination of microgram per litre level of manganese has been developed, based on Solid-Phase Spectrophotometry (SPS). Manganese reacts with 3-bromobenzohydroxamic acid to form a 1:3 anionic brown-reddish complex of Mn(III), which is fixed on a dextran-type anion-exchange resin. Resin phase absorbance is measured directly and allows the determination of manganese in the range 5–100 μg 1−1, with a RSD of 4%. The method has been applied to the determination of manganese in different samples, namely plant tissue extracts, active charcoals and waters.
