Sulfide in wastewater with Metrosep A Supp 10 - 100/4.0 and amperometric detection

Ion chromatographic determination of sulfide in wastewater is performed using amperometric detection and an alkali eluent to ensure the stability of the sulfide. Measurements are performed in single-potential or direct current (DC) amperometric mode. It is the best-known and most sensitive amperometric measuring method and also provides, in addition to a high selectivity, a large selection of working electrodes.

Sulfide determination is performed on a Metrosep A Supp 10 - 100/4.0 type column; a silver electrode is used as the working electrode.
