Infrared Spectrometer For Oil Content In Water Analyzer

Scope of application:

This instrument is suitable for the detection of total oil, petroleum or animal and vegetable oil content in various water bodies such as surface water, groundwater, industrial wastewater, domestic sewage, seawater, fishery water, farmland irrigation water, etc. The testing and testing principles are in full compliance with the current testing standards for the above-mentioned various industries or water bodies.

Detection principle:

According to the HJ637-2018 standard, the oil in the sample was extracted with tetrachloroethylene to determine the total oil, and then the extract was adsorbed with magnesium silicate to remove polar substances such as animal and vegetable oils, and then the petroleum was determined. The contents of total oil and petroleum are determined by wavenumbers of 2930 cm-1 (stretching vibration of CH bond in CH2 group), 2960 cm-1 (stretching vibration of CH bond in CH3 group) and 3030 cm-1 (stretching vibration of CH bond in aromatic ring), respectively. Bond stretching vibration) absorbance at the bands A2930, A2960 and A3030 were calculated. The content of animal and vegetable oils is calculated as the difference between the total extract and the content of petroleum.

Parameter index:
