Total organic carbon is a common indicator of water quality of organic matter in water. It represents the total amount of organic matter in water by carbon content. In fact, there are many types of organic matter in water, but these elements cannot be com

Phosphorus is a common element in surface water or various wastewaters. Under normal circumstances, the content of natural water is relatively small. It mainly exists in various industrial wastewater and domestic wastewater in the form of phosphate. The p

In daily water quality testing, nitrate can use disulfonic acid phenol photometry or ultraviolet photometry, but both of these methods can only measure drinking water and groundwater with a small content. As for sewage or industrial wastewater with a larg

Most of the benzene series are found in the atmosphere, so the detection of this substance is mostly found in the air standards, but the content of benzene series in industrial wastewater is also very large, so the content of benzene series in the water q

Faced with the current severe water use situation, in order to cope with the declining groundwater resources, the country has begun to vigorously promote the use of reclaimed water in recent years. The country’s current utilization rate of recycled water

In the previous content, we explained how to use spectrophotometry to detect the lead content in water, but no matter which part of the operation, as long as you are not careful, it will affect the final detection result. Therefore, if you want to obtain

We have introduced to you that you can use atomic absorption spectrometry to detect the heavy metal lead content in water. The advantage of this method is that the preparation of reagents is simple and the operation steps are simple, but the shortcomings

In order to improve the utilization rate of seawater resources, seawater has begun to gradually replace freshwater in some applications in order to promote the optimization of the structure of water resources. Seawater is mostly used for cooling treatment

Problems that need to be paid attention to when collecting and processing water samples1. This method can still be used for water samples with BOD5 greater than 6000mg/L, but because dilution will cause errors, it is necessary to require careful explanati

Sulfides in drinking water mainly come from the dissolution of underground minerals and the decomposition of microorganisms in water under anaerobic conditions. In addition to the above two types of sulfide in rivers, a part of it comes from domestic sewa
