Technical principles^-1Based on HJ637-2018 "Determination of Water Quality - Petroleum and Animal and Vegetable Oils - Infrared Spectrometric Method". Under the condition that the pH of the water sample is ≤ 2, tetrachloroethylene is used as the extraction agent, and high-speed rotary mixing extraction technology is used to extract the oil substances in the water body with a certain proportion of the extraction solvent. Then, the extraction solvent is dehydrated and introduced into the analysis tank to determine the oil content; After removing polar substances such as animal and vegetable oils by adsorbing the extract with magnesium silicate, determine the petroleum content. The content of oil and petroleum is determined by wave numbers of 2930cm₂（CH^-1Stretching vibration of C-H bond in functional group), 2960cm₃（CH^-1The stretching vibration of C-H bond in the functional group and 3030cm

3. Calculate the absorbance A2930, A2960, and A3030 at the stretching vibration of the C-H bond in the aromatic ring based on the correction coefficient; The content of animal and vegetable oils is the difference between the content of oil and petroleum.

application area

4. Used for the determination of petroleum and animal and plant oils in industrial wastewater and domestic sewage.
