Phenol

PhOH

Applications

Industrial wastewater – where the presence of phenolic compounds in the industrial waste water adversely affects aquatic and human life directly or indirectly when discharged into public waterways, water sources or surface water.

Description

The determination ranges of the phenol analyzer vary from trace μg/L to 250 mg/L using the (optional) internal dilution module.

Method

The colorimetric determination of phenol in water is based on the reaction of phenol with 4-amino-antipyrine in the presence of potassium hexacyanoferrate(III) buffer solution to form a red colored antipyrine complex. The absorbance intensity is proportional to the phenol concentration in the sample and is measured at 525 nm.
