The oil in the water includes petroleum and animal and plant species as well as other organic matter. When the oil pollutants in the water environment exceed the self-purification capacity of the water body, oil will be formed on the surface of the water body, blocking the oxygen from entering the water body, so that the dissolved oxygen content in the water body gradually decreases, resulting in the water body becoming black and smelly. Therefore, the relevant departments on the water oil content is an important standard to control emissions!

In this way, it is necessary to detect whether the content of oil in water meets the standard, and this chapter water quality online monitoring instrument manufacturers to understand together with you to monitor the oil content in water can not be separated from the instrument: water oil online analyzer!

What are the Methods of Oil Detection in Water?

Infrared spectrophotometry and fluorescence. Infrared spectrophotometry is not only a widely used method at present.

Oil-8000-oil in Water online analyzer produced by Modi-Tech uses ultraviolet fluorescence method to measure the concentration of OIL molecules in water. Oil molecules are activated into an excited state under specific ultraviolet light, which is very unstable and will soon return to the ground state. In the process of returning to the ground state, radiation fluorescence will be produced, and the concentration of oil molecules in the water sample is proportional to the intensity of radiation fluorescence emitted. The water sample is sent to the colorimetric tank after the pretreatment device. The light source is parallel to the oil molecules in the colorimetric tank water sample, and the resulting fluorescence is irradiated on the fluorescence sensor. Before the ultraviolet light is emitted and the fluorescence sensor is received, an accurate filter system is installed to control the emission wavelength of ultraviolet light and select the specific fluorescence wavelength scattered back by the received oil molecules. The received fluorescence intensity corresponds to the concentration of oil in the water sample to a certain extent, and the linear relationship can be made clearer by the selection and control of the transmission and reception wavelength of the filter light system.
