The permanganate index in water is generally used to detect relatively low chemical oxygen demand values, such as tap water, well water and other relatively clean water quality. This type of water quality has relatively low chemical oxygen demand. Permang

Potassium bromate is a colorless crystal or white crystalline powder. It has a wide range of uses. It can be mainly used for water quality testing and calibration reagents, oxidants, bleaching agents, etc. It has strong oxidizing properties, easily solubl

BOD is also called Biochemical Oxygen Demand, which refers to the dissolved oxygen consumed during the decomposition of certain oxidizable substances by microorganisms in water under specified conditions, especially the decomposition of organic substances

Residual chlorine in water is commonly used as a disinfectant, usually in the form of liquid chlorine. After liquid chlorine interacts with microorganisms, bacteria or reducing substances in the water, the amount of chlorine remaining in the water is call

Many auxiliary instruments are used in water quality testing. The volumetric flask is the most common instrument. The volumetric flask is a narrow-necked pear-shaped glass container with a stopper with a precise volume scale, made of colorless or brown gl

Redox is one of the commonly used methods in water quality testing. It is mainly used to detect the parameter changes of dissolved oxygen in drinking water. Compared with other methods, redox titration has the advantages of easy operation and low cost. R

When using a water quality detector, it is often necessary to prepare some reagents into the required concentration solution. The solution used in practical applications can be divided into three types: general solution, standard solution and buffer solut

The concept of acid-base titration Acid-base titration is a titration analysis method based on acid-base reaction. It is one of the main and basic titration analysis methods. The essence of acid-base reaction is the reaction of proton transfer. According

The common water pollution in rivers and lakes is mostly caused by the substandard discharge of various sewage, especially the unauthorized discharge of some industrial sewage, which will cause great pollution to the surface water quality. Therefore, it

At present, the trend of water quality monitoring technology to automation is very obvious, especially water plants, sewage treatment plants, rivers and lakes, etc. have begun to adopt online real-time water quality monitoring systems. This can save a lot
