Folded filter
 
Citric acid 5 % aqueous solution:
Dissolve 5 g Citric acid for analysis with 100 ml water for analysis.
 
Sample preparation:
Stir mechanically 5 g of the material with 100 ml of 5 % citric acid solution (30 min). After filtration through a folded filter determine the iron content directly.
 
Analysis:
Determine with the above mentioned test kits.
 
Calculation:
Iron content in mg/kg Fe = analysis value in mg/l Fe x 20
