The infrared water oil analyzer is mainly used to detect the content of pollutants such as petroleum, animal and vegetable oils, and catering fumes in water bodies. It is suitable for scenarios such as groundwater, surface water, industrial wastewater, and sewage treatment. It is an analytical instrument based on infrared spectroscopy technology used to detect the content of oil substances in water bodies. The core principle is to use the absorption characteristics of hydrocarbons in oil substances for specific wavelengths of infrared light, and quantitatively analyze oil concentration by measuring the absorbance value.
Hydrocarbons in oil substances have characteristic absorption peaks in the 3.4 to 3.5 micron wavelength range. The infrared oil analyzer measures the absorbance of the sample in this band, and combines the absorbance values of the standard three wavenumbers (2930cm ⁻¹, 2960cm ⁻¹, 3030cm ⁻¹) to calculate the content of total oil, petroleum, and animal and vegetable oils.
Testing process:
Extraction: Use solvents such as tetrachloroethylene to extract oil substances from water samples.
Separation: Use magnesium silicate adsorption to remove polar substances such as animal and vegetable oils, and separate petroleum products.
Measurement: Scan the infrared spectrum of the extraction solution and calculate the oil concentration based on the absorption peak position and absorbance value.
Application field
Environmental monitoring: Monitor oil pollution in natural water bodies such as rivers, lakes, and seas, and assess water quality. Detect whether the sewage discharge meets the standards and assist the environmental protection department in law enforcement.
Industrial wastewater treatment: in petrochemical, shipbuilding, port and wharf industries, monitor the oily wastewater generated in the production process. Assist sewage treatment plants in optimizing treatment processes to ensure that effluent quality meets standards.
Aquaculture: Detecting the oil content in aquaculture water to prevent oil pollution from causing harm to aquatic organisms. By adjusting the management measures of aquaculture water bodies, the yield and quality of aquaculture can be improved.
Research experiment: Study the distribution, migration, and transformation laws of oil in water, providing scientific basis for water ecological protection and pollution control.
