Common reducing inorganic substances such as ferrous salts, sulfides, and nitrites in water and organic substances oxidized under these conditions can consume potassium permanganate. Therefore, some people regard the index of permanganate as the water bod

Oxygen is one of the main components of the atmosphere. Because surface water is directly exposed to the air, it also contains a certain amount of oxygen. We call the oxygen dissolved in water the dissolved oxygen, and every liter of water contains oxygen

1. How to use the pH meter1. According to the requirements of the instrument manual, turn on the power, press the power button, and the instrument will warm up for 30 minutes.2. To install the electrode, first clamp the electrode clip on the electrode rod

Iodometry is a relatively high measurement method when detecting dissolved oxygen in water quality, but this type of method is mainly suitable for water with relatively high cleanliness such as source water and surface water. For some seriously polluted i

When testing the turbidity parameters of water quality samples, the ability to accurately prepare a standard solution of formazin is a weight technology to ensure the accuracy of turbidity measurement results. Therefore, as a qualified water quality inspe

Turbidity is an important parameter for the detection of drinking water. Generally, water plants will measure turbidity in all aspects, especially in the water outlet there are online real-time monitoring of turbidity instruments. The inspector can judge

In actual operation, the platinum-cobalt colorimetric method is only suitable for surface water, groundwater, domestic water, etc., which cannot be less serious water quality color detection. If it is more seriously polluted surface water and industrial w

Chromatography is called chromatography or chromatography. It is a physical and chemical analysis method that uses different distribution coefficients of components between two phases to separate. It is the most widely used and most effective in water env

Most of the phosphorus in natural water bodies comes from domestic sewage, animal husbandry wastewater, fertilizer loss from farmland, and industrial wastewater discharge. Among them, phosphorus pollution in domestic sewage accounted for 43%. Everyone kno
