Nanga def! Man furnisër dodecylphenol laa, te leegi ñu ngi may laaj lu bari ci anam yi dodecylphenol di yàqee. Kon ma xalaat ni damay jël sama jotu séddoo li ma xam, ba noppi xaaj ko ci anam wu yomb ñu xam.
Nanu njëkka wax luy dodecylphenol. Benn xeetu alkylphenol la, muy benn composé chimik bu am benn bague phenol bu am groupe alkyl bu ci nekk. Sudee dodesilfenol la, grupu alkil bi dafay nekk caden dodesil, muy caden bu am 12 karbon. Dodecylphenol dañu koy faral di jëfandikoo ci anam yu bari, lu ci melni defar ay detergent, ay emulsifikatër ak ay antioxydant.
Leegi nanu dugg ci anam yi mbir yi di yàqee. Barina anam yu dodecylphenol mëna yàqu, te mingi aju ci anam wi environmaa bi di doxee.
1. Biodegradasioŋ
Biodegradasioŋ bi bokk na ci anam yi gëna am solo yu dodecylphenol mëna yàq ci environmaa bi. Microorganism yu melni bakteri ak champignon yi dañu am solo lool ci mbir mii. Mikro-organism yooyu mën nañu jëfandikoo dodecylphenol ngir am karbon ak energie. Dañuy dindi molecule dodecylphenol ci ay reaksioŋ enzymatique yu bari.
Ci misaal, yenn bakteri yi mën nañu oxide chaîne alkyl bu dodecylphenol, diko wàññi ndànk-ndànk. Jamono di dox, molecule bi dafay gëna ndaw, gëna yomba yàqu. Ni biodegradation bi di doxee mën na wuute ci yenn mbir yu melni tàngoor, pH, ak bariwaayu ferñeent yi. Daanaka tàngoor wu gëna tàng ak pH bu amul benn boor ñooy gëna gaaw ci biodegradation.
2. Fotodegradasioŋ
Fotodegradasioŋ dafay am su dodesilfenol nekkee ci leeralu jant bi, rawatina radiasioŋ ultraviolet (UV). Leer UV amna doole ju doy ngir dog lëkkaloo chimik yi ci biir molecule dodecylphenol bi. Su loolu amee, molecule bi mën na am reacsioŋ yu bari, lu ci melni oxidation ak cleavage.
Reaksioŋ oxidation yi mën nañu dugal ay atomu oxygen ci biir molecule bi, mu soppi màndarga chimik yi ci nekk. Reaction cleavage mën na xaaj molecule bi ay pàcc yu gëna ndaw. Produit yi bawoo ci fotodegradaasioŋ mën nañu wuute ak yi bawoo ci biodegradaasioŋ. Fotodegradasioŋ mooy gëna bari lumuy xew ci ndox yi ci kaw suuf ak ci jawwu ji, di barab yu naaj wi di laal.
3. Oxidaasioŋ chimik
Oxidation chimik beneen mekaniism la buy yàq. Ci biir environmaa bi, barina mbir yuy oxide lu ci melni ozone, peroxyde hydrogène, ak yenn ion wen. Agent oxidant yooyu mën nañu jaxasoo ak dodecylphenol ba noppi diko yàq.
Ci misaal, ozone oxidant bu am doole la. Su ozone bi daje ak dodecylphenol, mën na jaxasoo ak ñaari lëkkaloo yi ci biir ring phenol bi ak chaîne alkyl bi. Loolu moo jur produit yu oxidé, yu gëna polar ak di seey ci ndox, moo gën molecule dodecylphenol bi njëkk. Yooyu produit yu gëna polar ñoo gëna yomba yàqu wala ñu dindi leen ci environmaa bi.
4. Hidrolise
Hydrolyse mooy li molecule ndox yi di dagg lëkkaloo chimik yi ci biir dodecylphenol bi. Doonte dodecylphenol mën na xeex hydrolyse ci anam wu jaar yoon, amna mbir yu mëna yokk hydrolyse bi. Ci misaal, su amee asid wala base yu dëgër, reaction hydrolyse bi mën na gaaw.
Sudee ci anam yu asid la, grupu phenol bi ci dodecylphenol bi mën na proton, suko defee molecule bi gëna yomba song ndox mi. Su amee anam wu yomb, ion hydroxide yi mën nañu jaxasoo ak molecule bi, loolu mooy tax yenn lëkkaloo yi xaajaloo. Waaye, hydrolyse dafay gëna néew lumuy yàqu sunu ko méngale ak biodegradasioŋ ak fotodegradasioŋ ci environmaa naturel yu bari.
Leegi, lu tax mu am solo ñu xam anam yi mbir yi di yàqee? Waaye, soo koy seet ci wàllu furnisër, daf nuy jàppale nu gëna xam li dodecylphenol mëna jur ci environmaa bi. Xam-xam boobu lu am solo la ngir mëna wax ni ñuy jëfandikoo sunuy produit ci anam wuy wàññi loraange yi ñuy yàq ci environmaa bi.
Sunu kiliyaan yi, xam anam yi mbir yi di yàqee mën na nekk lu am njariñ. Sooy jëfandikoo dodecylphenol ci benn aplikaasioŋ, danga wara xam naka lay def ci environmaa bi ginaaw boo ko jëfandikoo. Loolu mën nala jàppale nga jël yenn dogal ci wàllu jëfandikoo mbalit mi ak aar environmaa bi.
Soo bëggee gëna xam ci test degradaasioŋ dodecylphenol, mën nga xool lii:4-testdfgsdfg. Dafay joxe yenn leeral yu xóot ci - ci anam yi ñuy saytoo ak njariñ yi jëm ci yàqu-yàqu dodecylphenol.
Nun furnisër dodecylphenol lañu, danuy liggéey ngir joxe produit yu baax - ba noppi fexe ñu jëfandikoo leen ci anam wu baax te baax ci environmaa bi. Soo nekkee ci marse dodecylphenol wala nga am laaj bu jëm ci màndargaam, jëfandikoo gi, wala anam yi muy yàqee, bul sax xaar jokkoo ak nun. Dina nu kontaan lool ci waxtaan ak yaw ngir xam naka lañu mëna def ba mëna faj sa soxla. Doonte defarkat - bu ndaw nga wala liggéeyukaay bu mag, noo ngi fi ngir jàppale la.
