Reinventing volumetric Karl Fischer titration: OMNIS KF!
Iron in boiler feed water for power plants (DHN method)
Main document
The concentration of Fe(total) in boiler feed water is determined by adsorptive stripping voltammetry (AdSV) with 2,3-dihydroxy-naphthalene (DHN) as complexing agent. All reagents have to be added in the order as listed below. All reagents typically contain iron impurities, especially the DHN. Therefore a subtraction of the reagent blank is recommended.
