At present, if you want to know whether surface waters such as rivers, lakes, and reservoirs are eutrophic, you can judge by detecting the content of nutrients such as phosphorus and nitrogen in the water, or by observing the reproduction of algae in the

The country has given methods for the detection of sulfide and cyanide in reclaimed water in relevant standards, such as the 2019 standard for the determination of sulfide and cyanide in reclaimed water quality by ion chromatography. The ion chromatograph

Reclaimed water generally refers to the water body whose water quality index reaches the corresponding use standard stipulated by the state after a series of purification treatment of wastewater or other sewage. At present, domestic reclaimed water is mai

Gas chromatography can detect the content of 12 chlorobenzene compounds in surface water, groundwater, drinking water, seawater, industrial wastewater and domestic sewage. The principle is to use carbon disulfide to extract chlorobenzene compounds in wate

The principle of liquid chromatography-mass spectrometry for the detection of butylxanthogen in surface water, industrial wastewater and other water quality is to separate the butylxanthogen in water samples by liquid chromatography, and then use a tandem

Enterococci in water are also called gram-positive cocci, which are widely distributed in the natural environment and in the digestive tract of humans and animals. Therefore, there are also such species in common surface water. At present, many methods ca

Most of the anionic surfactants in reclaimed water come from various industrial wastewaters. In industrial production, it can be used as flocculation and sedimentation, such as wastewater from grain alcohol production, wastewater from papermaking process,

Generally, most of the methods for detecting COD in water have strict requirements on the content of chloride ions. Because chloride ion is currently the biggest interference factor in COD water quality testing, although there are some treatment methods i

I believe that antibiotics are familiar to everyone. As an anti-inflammatory drug, it is widely used in the treatment of various diseases, but the harm of abuse is also obvious; and in recent years, in addition to European and American countries, antibiot

In some microbiology laboratories or places that require aseptic operation, the help of biological indicators is needed to understand the specific effect of sterilization. Usually, sterilization refers to killing all target microorganisms by physical or c
