Abstract
Aqua-regia method is reported for simultaneous determination of potassium, sodium, calcium, magnesium, zinc, manganese, copper and iron in high-fat fish tissue. Samples are digested with conc nitric and conc hydrochloric acid in a volumetric flask. After digestion, aqua-regia extracts of samples are analyzed by direct flame atomic absorption spectrophotometry. The aqua-regia method is compared with dry ashing method and
