Search for the four digit reagent code number listed on the reagent label, in the contents
list or in the test procedures. Omit any letter that follows or precedes the four digit code
number. For example, if the code is 4450WT-H, search 4450. To obtain a printed copy,

Aluminum is the third most common element in the earth’s crust, which accounts for
its wide appearance in many water supplies. Aluminum exists in water as soluble salts,
colloidal compounds, and insoluble compounds. In wastewater that has been treated by
alum coagulation it will appear in one or more of the above forms. Properly treated drinking
water should have an aluminum concentration below 0.05 mg/L.
APPLICATION:
Drinking, surface, and saline waters; domestic and industrial
wastewater.
RANGE:
0.00–0.30 ppm Aluminum
MDL:
0.01 ppm
METHOD:
Aluminum ions buff ered to a pH of 6.0 react with Eriochrome
Cyanine R dye to produce a pink to red complex in proportion
to the concentration.
SAMPLE HANDLING &
PRESERVATION:
Collect sample in acid washed glass or plastic bottle. Analyze
as soon as possible.
INTERFERENCES:
Fluoride and polyphosphate will interfere. Interference from
iron and manganese is eliminated by the addition of an
inhibitor.
