Iron Reagent Set, 0,01 - 1,80 mg/L Fe

Description

Reagent Set Powder Pillows reagents (2544800) for the determination of Iron from Hach.

Аpplication: For cooling water that contains molybdate-based treatment.

The reagents are hermetically sealed in foil sachets, which provides them with a long shelf life. The reagent is simply poured into the measuring cuvette along with the sample. The analysis is carried out visually, for example using a color disc or with a HACH LANGE photometer.

Summary of method: FerroMo Iron Reagent 1 contains a reducing agent combined with a masking agent. The masking agent removes interference from high levels of molybdate. The reducing agent converts precipitated or suspended iron, such as rust, to the ferrous state. FerroMo Iron Reagent 2 contains the indicator combined with a buffering agent. The indicator reacts with ferrous iron in the sample, buffered between pH 3 and 5, which results in a deep blue-purple color. The measurement wavelength is 590 nm for spectrophotometers or 610 nm for colorimeters.
