Anions in FGD Gypsum According to VGB-M 701e

Flue gas desulfurization (FGD) gypsum is produced in power stations. VGB-M 701e (2008) describes aqueous extraction methods for the ion chromatographic determination of chloride in FDG gypsum. This application note demonstrates VGB sample preparation and how it can be utilized to determine other anions than chloride.
