Iron analysis in heat exchanger water
Thread Content
Do any of you have analysis methods for iron in circulating water? Due to concerns regarding the corrosive effect of acetic acid on the equipment, it is now necessary to analyze the iron content in the circulating water containing a small amount of C4. Since the water sample has a slight yellow color and contains some sediment, what method would be suitable for this analysis? Currently, only the 723 and 721 spectrophotometers are available
The method involves acidifying the sample and reducing the trivalent iron ions, followed by colorimetry using the o-phenanthroline method. A regular photometer can measure iron ions without any problems; it may be necessary to dilute the sample as well. There should be standard methods for measuring iron in circulating water; one can look up the relevant standards.
Are there specific methods and steps to follow?

If even the standard methods require someone else to provide them, then please pay some money. I’ll tell you for free the standard method number GB/T14427 – Methods for analyzing water used in boilers and cooling systems: Determination of iron
