• 4-Aminoantipyrine Method (4-AAP)—References: APHA Standard Methods, 14th ed., p. 574, Method 510 C (1975). ASTM D 1783-01, Phenolic Compounds in Water, Test Method B. USEPA Methods for Chemical Analysis of Water and Wastes, Method 420.1 (1983)
• Phenol (hydroxybenzene) is the simplest of a group of similar organic chemicals, which includes cresols, xylenols, and catechols
• Phenol itself is a common ingredient of disinfectants
• In drinking water, low-level phenolic concentrations impart a foul taste and odor, especially upon chlorination
• High phenol concentrations can indicate contamination from industrial effluents or waste discharge
• Method is applicable to the monitoring of phenolic compounds in wastewater.
• Phenolic compounds react with 4-AAP in alkaline solution in the presence of ferricyanide to produce a red reaction product
• Phenol, meta-, and ortho-substituted phenols, and some para-substituted phenols, under proper pH conditions, are detected with this method
• Results are expressed as ppm (mg/L) phenol

• Cardboard box
• Refill reagent ampoules for 30 tests
• 25 mL sample cup
• Ampoule blank
• Instructions
• Calibration table
