2449300 Hach

High Range Total Iron Reagent Set measures total iron in water, wastewater and seawater.

Add to bag

Article 2449300 measures total iron in the range from 100 to 1000 mg/L Fe in water, wastewater and seawater. The product uses TitraVer Titration method (8214). Each package of the product can be used to analyze up to 100 tests.

High Range Total Iron Reagent Set includes:

Before starting analysis:

  • It is required to collect the sample in clean glass or plastic containers.
  • It is recommended to use TitraStir Titration Stand to hold the Digital Titrator and stir the sample.

Procedure for Fe measurement

Select sample volume and titration cartridge (required sample volumes and digit multipliers may be found in the manual). Insert delivery tube into the digital titration cartridge and attach the cartridge to the Digital Titrator. Then swirl the sample and the content of the Citrate Buffer Powder Pillow in the 125mL Erlenmeyer flask. After that add Sodium Periodate Powder Pillow and mix the content of the 125mL Erlenmeyer flask. Pour Sulfosalicylic Acid Powder Pillow and swirl to mix. Add titrant until the color changes from red to yellow and calculate the concentration.

Summary of method

Ferrous iron Fe2+ is oxidized by sodium periodate to ferric ion Fe3+ that develops red complex with sulfosalicylic acid. The red complex is removed by titration with EDTA. Citric acid buffers the solution and makes the ferric ion stable in the solution.
