Παράµετρος :

Παρεµποδίσεις :
Positive interferences may be caused by arsenate (AsO₄³⁻) and, under heated conditions, by silica or silicate (SiO₄-)
Reducing substances such as sulfide (S²⁻), thiosulfate (S₂O₃²⁻), thiocyanate (SCN⁻), and excess molybdate (MoO₄²⁻) may interfere at high concentrations. The following ions do not cause interference at concentrations up to 1,000 mg/L: aluminium, ferric iron, magnesium, calcium, barium, strontium, lithium, sodium, potassium, ammonium, cadmium(II), manganese(II), lead(II), mercury(I), mercury(II), tin(II), copper, nickel, silver(I), uranium(IV), zirconium(IV), arsenite, bromide, carbonate, perchlorate, cyanide, iodate, nitrate, nitrite, sulfate, sulfite, pyrophosphate, tetraborate, selenate, benzoate, citrate, oxalate, lactate, tartrate, formate, and salicylate.
Large quantities of color and turbidity interfere. Fats, oil, proteins, surfactants and tar interfere.
