How does Ferrozine Sodium detect iron?

It reacts selectively with Fe2+ ions to form a stable magenta complex. The colored complex can be measured by UV-visible spectrophotometry, allowing ferrous iron to be quantified without requiring organic extraction.

What wavelength is used for the Fe2+-Ferrozine complex?

The Fe2+-Ferrozine complex is commonly measured at approximately 562 nm. Absorbance at this wavelength is used to calculate the ferrous iron concentration in the sample.

Is Ferrozine Sodium the same as PDT disulfonate?

PDT disulfonate is a common synonym for the ferrozine compound represented by CAS 69898-45-9. Both names refer to the water-soluble triazine sulfonate reagent used for ferrous iron determination.
