Water quality volatile phenol detection reagentPhenolic compounds are important chemical raw materials with a wide range of applications. Phenols and their homologues, as toxic pollutants emitted in various industrial production processes, are difficult to biodegrade in the environment and have become a common type of pollutant in the environment. Phenolic compounds can be divided into volatile phenols and non-volatile phenols according to their boiling points. Volatile phenols mostly refer to phenols with boiling points below 230 degrees Celsius that can evaporate with water vapor, mainly including phenol, p-nitrophenol, and p-aminophenol.

measuring range

matters needing attention

1. If the content is higher than the reagent range, the measured value can only be used to estimate the dilution factor and cannot be used as a test result. After diluting the sample, retest;

2. The pH value of the water sample to be tested should be 4.0-9.0. If it is not within this range, dilute acid or dilute alkali should be used for adjustment;

3. The reagent contains cyanide salts, and the reagent and test waste liquid should be properly stored and treated. They should not come into contact with acidic compounds, and should not be directly discarded or poured into water;

4. Various impurities in the water sample can affect the test, please refer to the relevant instructions on interference factors for details;

5. Store in a dry, cool place, out of reach of children. Do not store with food, medicine, etc., and do not put into fire.
