Cat.No. 114896  Spectroquant® Iron Cell Test
Cat.No. 116754  Water for analysis
As a rule the iron in these situation is in ionic form, therefore a special prior decomposition is not necessary.
Sample preparation:
In a 1000-ml volumetric flask place 10 ml of the filtered test solution, fill up to the mark with water for analysis and mix well. Place 10 ml of this solution in a 1000-ml volumetric flask and fill up to volume with water for analysis. The total dilution is 1:10000.
Determine with the above mentioned test kit.
Iron content in g/l Fe = analysis value in mg/l Fe x 10
