Abstract
The influence of 8 mineralisation (dry and wet ashings) procedures on the determination of the mineral content of the brown seaweed Undaria pinnatifida by atomic absorption spectrophotometry was studied. Two pr ocedures are proposed for routine analysis: dry ashing using sample ca lcination at 450-degrees-C, followed by ash treatment with hydrochlori c acid and silica elimination by hydrofluoric acid, and wet digestion using hot nitric acid.
