Automated Photometric Determination of Manganese using the Metrohm’s Optrode Sensor

This application note describes the use of Metrohm’s Optrode Sensor for titration, with photometric endpoint recognition in the determination of Manganese. Manganese can be determined as Mn(II) in aqueous solutions at pH 10 with Eriochrome Black T as indicator; the Optrode is used at a wavelength of 610 nm.
