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
METHOD: Aluminum ions buffered to a pH of 6.0 react with
Eriochrome Cyanine R dye to produce a pink to red complex
SAMPLE
HANDLING &
PRESERVATION:
in proportion to the concentration.
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.
