Compound disinfectant

Non-oxidizing fungicides do not kill microorganisms by oxidation, but are toxic to special parts of microorganisms, so they are not affected by reducing substances in water

(1) Inorganic and inorganic compound bactericide

Although the silver ion disinfectant has high antibacterial activity, it reduces the commercial value of the product due to the blackening and discoloration of Ag ⁺ ; the nano-TiO ₂ photocatalytic disinfectant is cheap and safe, but it uses solar energy with low efficiency and is easily affected by electrons and air.

(2) Organic-organic compound disinfectant

Hou Qingshun and others overcame any problems by mixing chitosan, dioctadecyldimethylammonium chloride, didecyldimethylammonium chloride and dodecyldimethylbenzylammonium chloride in proportions.

(3) Organic-inorganic compound disinfectant

Use organic ligands with antibacterial properties and inorganic cations/silver ions with antibacterial properties to form composite salt disinfectants, such as triiodooxy compounds, Ni(I), Cu(I), Zn(I) of tetrathiosemicarbazone The synthesis of chelate, etc.
