Phenols Vacuettes Refill, 4-Aminoantipyrine, Range: 0-120 & 0-1,400 Ppm, Each

Details:

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.The 4-aminoantipyrine methodreferences: apha standard methods, 14th ed., 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).Chemetrics' phenols kits employ the well-established 4-aminoantipyrine (4-aap) method. 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. The method is applicable to the monitoring of phenolic compounds in wastewater. Results are expressed as ppm (mg/l) phenol.
