title: [Extraction method for the simultaneous determination of sodium, potassium, calcium, magnesium, iron, copper, zinc and manganese in organic material using atomic absorption spectrophotometry (author's transl)].
abstract: Determination of sodium, potassium, calcium, magnesium, iron, copper, zinc, and manganese in organic material is possible with one digestion using the described extraction method. Data for sodium, potassium, calcium, magnesium, iron, and manganese agree well with those obtained by conventional methods [1, 2, 4]. For quantitative determination of copper and zink the extraction method is superior to dry ashing at 450 degrees C [1, 4]. In general the extraction method ist preferable to dry assing, because the amount of sample, time and costs can be reduced essentially using the described method.
