Chemical specific deoxidizer is a chemical agent used to remove oxygen from water, commonly used in various chemical processes, especially in reaction, storage, and treatment systems that require low oxygen environments. The following are some common chemical specific deoxidizers:
Sulfite type deoxidizers: For example, sodium sulfite (Na2SO3) or sodium bisulfite (NaHSO3). Sulfite can undergo a reduction reaction with oxygen to generate sulfur dioxide, thereby removing oxygen from water. These deoxidizers are commonly used in chemical processes, especially for reactions that are sensitive to oxygen.
Polymer organic deoxidizers: These deoxidizers are usually polymer compounds containing active groups, such as polyethylene imine (PEI) and polyethylene glycol (PEG), which can adsorb oxygen molecules and form insoluble precipitates in water to achieve deoxygenation. This type of deoxidizer is particularly suitable for chemical processes that require long-term low oxygen environments.
Nickel catalyst deoxidizer: This type of catalyst typically uses hydrogen gas as a reducing agent, catalyzing the reaction of oxygen and hydrogen gas to generate water, thereby removing oxygen from the water. Nickel catalysts are widely used in petrochemical and chemical synthesis processes, especially in hydrogenation reactions and gas treatment.
It should be noted that the specific selection of chemical specific deoxidizers should be based on actual application needs and operating conditions. When using deoxidizers, it is necessary to follow the instructions on the product label and safety operation guidelines, follow the correct ratio and usage methods, and ensure the safe and effective removal of oxygen from water.
