Interferences: Oxidants like Bromine, Bromamine, Copper Cu(II) >8 mg/L, Chromate, Hydrogen peroxide, Iodine, Iodoamines, Iron Fe(III) >20 mg/L, Nitrite, Ozone and Manganese may oxidize the DPD colour solution.
Iodide and Bromide will interfere with determination of free Chlorine.
Reduced forms of these components – Chloride, Manganous ion Mn(II) and Oxygen – do not interfere.
Organic contaminants may produce a false Free chlorine reading.
Chlorine dioxide will be detected as Total Chlorine.
Reducing agents such as Ferrous compounds, Hydrogen, Sulphide and oxidizable organic matter generally do not interfere.
Large amounts of colour and turbidity interfere. Fats, oil, proteins, surfactants and tar.
