Abstract

A simple and sensitive spectrophotometric method for the determination of manganese(II) using o-hydroxyhydroquinonephthalein (On.Ph.) and tetradecyldimethylbenzylammonium chloride(zephiramine) was studied. The method could be used in the concentration range of 0-4.0 μg/10 ml of manganese(II), where the Sandell sensitivity was 0.00038 μg/cm² at 535 nm, and was applied to the determination of manganese(II) in tap water and waste water.
