Electrochemical Hydrogen Peroxide Sensors: Intelligent Monitoring Guards in the Chemical Industry

In modern chemical production, hydrogen peroxide (H₂ O₂), as an important oxidant, bleach and disinfectant, is widely used in synthetic reactions, wastewater treatment, pulp bleaching and other scenarios. However, the gas volatilized by hydrogen peroxide is highly oxidizing and corrosive, and can cause multiple injuries to the human body through respiratory tract and skin contact. Low concentrations of H₂ vapor can irritate the mucous membranes of the eyes, nose and throat, causing tearing, coughing and breathing difficulties; long-term exposure may lead to fibrosis or chronic inflammation of the lungs. If the concentration exceeds 75 ppm, it may cause acute pulmonary edema and even asphyxia. Hydrogen peroxide sensor based on electrochemical principle, with its high efficiency and sensitive characteristics, has become an indispensable monitoring tool in the chemical industry.

In chemical production, the application of H₂ O₂ sensors runs through many links, and its dependence is mainly reflected in the following aspects:

Leakage warning and safety protection: chemical plant storage tanks and pipelines are prone to H? O? leakage due to corrosion or pressure fluctuations. Wall-mounted sensors can be deployed in key areas, combined with sound and light alarm devices, when the concentration exceeds the exhaust system or emergency shutdown, to prevent the accident from expanding.

Environmental compliance and emission monitoring: The waste gas treatment process needs to monitor H? O? residues to avoid excessive emissions and environmental pollution. For example, in the flue gas emission system, the sensor combined with the pretreatment device can accurately analyze the concentration of H₂ O₂ in the exhaust gas, helping enterprises to meet the requirements of environmental regulations.

In addition, the maintenance convenience of the sensor also enhances its dependence, ensuring long-term stable operation of the equipment.
