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 sedom
contain more than 1 mg/L phenol.
APPLICATION: Drinking and surface waters; domestic and industrial waste
water.
RANGE: 0.00–6.00 ppm Phenol
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 acidification with phosphoric acid to pH 4.0.
INTERFERENCES: Oxidizing and reducing chemicals, alkaline pH values, and
phenol decomposing bacteria may interfere with the test.
