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,

Manganese is present in ground water in the divalent state due to the lack of oxygen. In
surface waters, manganese may be in various oxidation states as soluble complexes or as
suspended compounds. Manganese is rarely present in excess of 1 mg/L. It may impart an
objectionable taste or cause staining problems in laundry, but manganese levels normally
encountered in water seldom produce any health hazards. Manganese is removed from
water by various means, including chemical precipitation, pH adjustment, aeration,
superchlorination and the use of ion exchange resins.
APPLICATION:
Drinking and surface waters; domestic and industrial
wastewaters.
RANGE:
0.0–15.0 ppm Manganese
MDL:
0.3 ppm
METHOD:
Periodate oxidizes soluble manganous compounds into
permanganate.
SAMPLE HANDLING &
PRESERVATION:
Manganese may oxidize readily in a neutral water and
precipitate from solution. It may adhere to or be absorbed by
container walls, especially glass. Acidifi ed samples can be
stored in plastic.
INTERFERENCES:
Reducing substances capable of reacting with periodate or
permanganate must be removed or destroyed before the
periodate oxidation is attempted.
