Product Overview:

Phenols can be classified into volatile and non-volatile phenols based on whether they can be distilled with steam. Volatile phenols generally refer to monophenols with boiling points below 230°C. Phenols primarily originate from wastewater produced in oil refining, gas washing, coking, papermaking, synthetic ammonia production, wood preservation, and chemical industries. Phenols are highly toxic substances, acting as protoplasmic poisons. Low concentrations can denature proteins, while high concentrations cause protein precipitation, directly damaging various cells and strongly corroding skin and mucous membranes. Long-term consumption of phenol-contaminated water may lead to dizziness, skin rashes, itching, anemia, nausea, vomiting, and various neurological symptoms. Phenolic compounds have been identified as tumor promoters in humans and mammals.

Product Principle:

In an alkaline medium, phenolic compounds react with 4-aminoantipyrine. In the presence of potassium ferricyanide, an orange-red antipyrine dye is formed. The instrument performs quantitative analysis using spectrophotometry.
