Instran Online Low Concentration Iron Ion Concentration Meter
Continuous measurement of low concentrations of iron ions in water is possible!
Method - Colorimetric Analysis After the sample is introduced into the measurement cell, several reagents are added to adjust the solution conditions (such as pH and the valence of elements). Subsequently, a blank measurement is conducted to correct for the effects of temperature and turbidity. Then, the final reagent is added, which reacts with the solution to produce a color that is measured at the appropriate wavelength. Depending on the photometer used, the results are obtained with very high precision. Trivalent iron (Fe³⁺) is reduced to divalent iron (Fe²⁺) by hydroxylamine hydrochloride. The divalent iron ions react with ferrozine in a buffer solution adjusted to a pH range of 5 to 7, forming a pink complex. This method allows for the measurement of very low concentrations of iron. The reagents used are stable. If it is necessary to measure total iron, the stirring time can be extended to ensure that the iron is completely dissolved in an acidic medium.
