Document Number: NL ISO 6332 : 2009

TC: No
ICS: 13.060.50
This International Standard specifies a 1,10-phenanthroline spectrometric method for the determination of iron in water and waste water. Procedures are described for the determination of a) total iron (sum of dissolved and undissolved iron) : 1) direct determination, 2) determination after decomposition; b) total dissolved iron [sum of dissolved iron(II) and iron(III)]; c) determination of dissolved iron(II). The methods are applicable to the determination of iron concentrations between 0,01 and 5 mg/l. Iron concentrations above 5 mg/l may be determined after suitable dilution of the sample. For interferences see clause 10.
