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,

Phenols may occur in domestic and industrial waste waters and in drinking water supplies.
Chlorination of waters containing phenols may produce odiferous and objectionable
tasting chlorophenols. Natural waters seldom contain more than 1 mg/L phenol.
Phenols may be removed from water by various treatment processes including
chlorination and activated carbon absorption.
APPLICATION:
Drinking and surface waters; domestic and industrial
wastewaters.
RANGE:
0.00–6.00 ppm Phenol
MDL:
0.05 ppm
METHOD:
4-Aminoantipyrine is oxidized in the presence of all ortho-
and meta- substituted phenols to form a colored complex in
proportion to the amount of phenol present.
SAMPLE HANDLING &
PRESERVATION:
Phenols are subject to biological and chemical oxidation.
Samples should be analyzed within 4 hours after collection. If
sample cannot be analyzed within 4 hours it can be preserved
by acidifi cation with phosphoric acid to pH 4.0.
INTERFERENCES:
Oxidizing and reducing chemicals, alkaline pH values, and
phenol decomposing bacteria may interfere with the test.
