Add acidic reagents to the water sample to dissolve the suspended iron, inject buffer, adjust to a suitable pH range, add reducing agents (such as hydroxylamine hydrochloride), reduce trivalent ferric ions in the water sample to divalent iron ions, and after the reduction reaction is complete, add a specific color developer (reacting with ferric ions to form colored complexes). The color intensity of this complex is proportional to the concentration of divalent iron ions.
Based on pre-established calibration curves or standard curves, the measured absorbance value is converted into total iron content. By precisely controlling the amount of reagent added and reaction conditions, combined with advanced measurement technology, accurate measurement of total iron content in water samples can be achieved.
