NIOSH 7056

BARIUM, soluble compounds

This method is designed to monitor Barium salt of nitric acid. This method uses atomic absorption (flame) to determine Ba 2+ in water-soluble barium compounds. Insoluble barium compounds (e.g.,BaSO4 ) require an ashing procedure. Wear protective clothing and work in a fume head. This revises Method S198.

Analysis Type (Application Method): Atomic absorption
