Nitric acid analyzer

Nitric acid analyzerThe measurement is carried out using wet chemistry method. Adopting dual channels, one channel collects HONO and interfering substances, while the other channel collects HONO+interfering substances+HNO3. The atmospheric nitric acid online analyzer uses cadmium reduction method to reduce nitrate ions to nitrite ions. The nitrite obtained from the two routes reacts with sulfonamide to form a diazonium salt solution, which is then mixed with a dye solution of naphthylethylenediamine hydrochloride to form an azo dye. Azo dyes pass through a long path absorption tube to obtain the concentration of nitric acid by measuring the absorbance of specific wavelengths of light.

Instrument features:

The automatic degassing system avoids the interference of bubbles on the instrument;

Liquid level alarm protection system to prevent liquid from being sucked into flow controllers (MFC), vacuum pumps, etc;

Automatic zero calibration effectively checks the stability of the instrument and whether the real-time concentration obtained is accurate.

Nitric acid analyzerIt is an instrument used to measure nitric acid concentration, which has important applications and usage significance in multiple fields.

Firstly, in the field of water resource security, it is possible to quickly and accurately detect the concentration of nitric acid in municipal drinking water, groundwater, rivers, lakes, and marine water sources. This helps drinking water treatment companies monitor water quality, timely and effectively identify and solve water quality problems, and ensure water source safety.

Secondly, in the field of industrial wastewater treatment, it is mainly used to monitor the concentration of nitric acid during the sewage treatment process. It can monitor changes in nitric acid concentration in water in real time, providing a basis for sewage treatment and ensuring that wastewater discharge meets environmental standards.

In the field of agriculture, real-time monitoring of nitric acid concentration in soil and water bodies during agricultural production. This helps guide farmers to reduce the use of fertilizers, prevent excessive levels of nitric acid in water and soil, thereby reducing pollution and protecting water resources.
