Formaldehyde may be allergenic and carcinogenic to the human body, and it can be ozonated by industrial wastewater and naturally occurring humus, and the concentration of formaldehyde in rainwater is expected to be three orders of magnitude higher than that in surface water, in fact, atmospheric deposition is an important source of formaldehyde in aquatic systems. The following small series of different places in the water formaldehyde detection problem!
Formaldehyde Detection in Drinking Water
Fatty acids enter drinking water mainly through the oxidation of natural organic materials such as humus in the process of ozone chlorination, and the protective layer leached from polycyclic aldehyde plastic parts has been destroyed, which is one of the resources of fatty acids in drinking water.
Formaldehyde Detection in Wastewater
Formaldehyde has been used as a key chemical in many industrial activities. In the organic synthesis industry, the synthesis of special chemicals such as pentaerythritol and ethylene glycol uses formaldehyde as one of the reagents. In addition, fatty acids are essential in the production of resins, textiles, paper products, pharmaceuticals and medicines. As a result, wastewater generated in these industrial applications may contain significant amounts of formaldehyde that need to be identified and treated.
Chemical Analysis of Formaldehyde in Hydration Wastewater
Since the concentration of formaldehyde in water can sometimes be high and may pose a potential risk to human health, we should take some methods to measure its accurate concentration. Chemical analysis of formaldehyde can provide meaningful information about water quality, so immediate action can be taken to ensure that water suppliers provide consumers with water that is safe to use and meets public recreational requirements when changes occur.
Formaldehyde online testing equipment in water!
HCHO-8000 Formaldehyde on-line analyzer is a fully automatic on-line analyzer controlled by embedded system, which can be applied to real-time on-line monitoring of formaldehyde content in various water quality. After the sample is filtered, it is pumped into the reactor, the masking agent is injected first to eliminate the interfering substances, and then the acidity of the solution is adjusted to make the solution have a suitable pH, and then the characteristic color developer is added to react with formaldehyde in the water for color development, and the absorbance of the reactants is measured. The content of formaldehyde in the sample is calculated by the size of absorbance.
