Interferences

Standard colors were determined from standard solutions. However, coexisting substances will

cause inaccurate results. The list below reports ion concentrations under which ones interferences

are insignificant:

≤ 1000 mg/L : B3+, Ca2+, Cl-, F-, I-, K+, Mg2+, Mo6+, Na+, NH4

+, NO2

-, NO3

-, PO4

3-, SO4

2-, Phenol,

Formaldehyde, Anionic surfactant

≤ 500 mg/L : Al3+, Ba2+

≤ 200 mg/L : Cr3+, Mn2+

≤ 100 mg/L : Residual chlorine

≤ 50 mg/L : Cr6+

≤ 10 mg/L : Ag+, CN-

≤ 5 mg/L : Co2+, Cu2+, Ni2+, Zn2+,
