The principle of sodium sulfate-hydrogen peroxide-sodium chloride adduct formaldehyde removal mainly involves the synergistic effect of chemical reaction and physical adsorption.

Firstly, hydrogen peroxide (H2O2) is the main component in sodium sulfate-hydrogen peroxide-sodium chloride adduct, which has strong oxidizing properties and can oxidize with formaldehyde. Under alkaline conditions, hydrogen peroxide can oxidize formaldehyde to formic acid, thereby reducing the concentration of formaldehyde in the room. This chemical reaction can effectively convert formaldehyde into a harmless substance, reducing its pollution to the air.

Secondly, the role of NaCl here is mainly to increase the ionic strength of water, which may help to enhance the adsorption capacity of water molecules to formaldehyde. Although the actual formaldehyde removal effect of salt water is relatively limited, it can help remove some formaldehyde through physical adsorption.
