Standard colors were determined from standard solutions. However, coexisting ions can modify

reaction color. The list below reports ion concentrations under which ones interferences are

insignificant:

≤ 1000 mg/L : Al3+, As3+, B3+, Ca2+, Cd2+, Cl-, F-, Hg2+, I-, K+, Mg2+, Mn2+, Na+, NH4+, NO2-, NO3-, Pb2+,

PO43-, SO42-, Zn2+, Phenol, Residual Chlorine

≤ 250 mg/L : Ba2+

≤ 100 mg/L : Sn2+

≤ 50 mg/L : Fe3+

≤ 20 mg/L : Cr3+

≤ 10 mg/L : Cr6+, Cu2+
