Quaternary Ammonium Munyu we Disinfectant

Quaternary ammonium salts (QAS) ndiwo macationic makomputa ane alkyl mapoka muketani pakureba kweC8-C18, ayo ari soluble yemvura uye anogona kushandiswa semishonga inouraya utachiona mumachira emachira.

QAS ioniic makomputa ane quaternary ammonium nitrogen, mana alkyl kana aryl mapoka akabatana neiyi nitrogen, uye anionic ion senge chloride kana bromide. Pakati pemapoka mana ealkyl, rimwe iboka rakareba reketani rine mahydrocarbon anopfuura masere uye rinoshandawo seboka rehydrophobic. Hydrophobic mapoka eQAS anowanzo kukanganisa mabasa avo antimicrobial (Tiller et al., 2001; Zhao uye Sun, 2007). Iine yakasimba hydrophobicity, iyo yakasimba simba antimicrobial inoshanda iyo QAS ine (Zhao neSuva, 2008) (Fig. 16.1 uye Tafura 16.1). Mazhinji makomputa eQAS ane anoshanda pamusoro. QAS inoshanda biocides painoshandiswa mune aqueous mhinduro uye semvura inouraya mishonga. Kana QAS yakabatana nemakemikari kune fiber nzvimbo, mabasa avo anogona kutadziswa zvichienderana nekuti akabatana sei uye ekupedzisira maumbirwo eQAS pane nzvimbo. Panyama inosanganisirwa QAS mumicheka inogona kupa antimicrobial mashandiro nekudzisunungura zvishoma nezvishoma kubva kumafibre epo panguva yekushandisa, izvo zvinogona kupa zvakatarwa mabasa echinhu.
