No replacement
Scope:

This method is for determining phenol at concentrations from 0.1 to 2.0 mass-ppm in light aromatic hydrocarbons such as benzene, ethylbenzene, cumene, toluene and xylene, as well as cyclohexane by visible spectrophotometry. Higher concentrations can be determined by diluting the sample. The presence of substituted phenols may cause a positive interference. Aldehydes, ketones, ethers, alcohols, amines, and sulfur compounds will interfere, if present.
