Water Quality Determination of Petroleum and Animal and Vegetable Oils by Infrared Spectrophotometry” According to the HJ637-2018 standard, the oily substances in water are extracted with tetrachloroethylene, the total extract is measured, and then the extract is adsorbed with magnesium silicate. After removing polar substances such as animal and vegetable oils, measure petroleum. The total extract and petroleum content are calculated from the absorbance at the bands of 2930cm-1, 2960cm-1, and 3030cm-1, respectively. The content of animal and vegetable oils is calculated based on the difference between the total extract and the petroleum content.
Technical advantages
- Only two suitcases, including an infrared oil meter, and a box of pre-processing equipment, can complete the field experiment project;
- The pre-processing box has built-in extraction equipment, and the sampling bottle is the extraction bottle, no need to transfer, just go on the machine directly, instead of manual extraction, it is more convenient to use;
- Equipped with a patented technology product standard oil filter, which can be permanently single-pointed for calibration, and a standard curve can be replaced for life without contact with toxic reagents;
- It can complete the volume of water samples and reagents, extraction, separation, vibration and adsorption of animal and vegetable oils or water and impurities with one button
