I-alumina esebenzayo

Kuye kwaba nentuthuko enkulu kwezobuchwepheshe bokususa i-fluoride ngokuthuthukiswa kwe-alumina adsorbent entsha eguquliwe nge-asidi. Le adsorbent entsha ibonise izakhiwo ezithuthukisiwe zokususa i-fluoride emanzini angaphansi komhlaba naphezulu, okubalulekile ekubhekaneni namazinga ayingozi okungcola kwe-fluoride okusongela kakhulu impilo yabantu.

I-fluoride eningi emanzini okuphuza iye yahlotshaniswa nezinkinga eziningi zezempilo, okuhlanganisa i-fluorosis yamazinyo namathambo, kanye nezinye izimo zempilo ezimbi. Njengoba izindlela zokwelapha amanzi zendabuko zibonakala zingasebenzi kahle ekususeni i-fluoride emanzini, ukuthuthukiswa kwe-adsorbent ephumelelayo kunikeza ithemba elisha ekubhekaneni nale nkinga ephuthumayo.

I-alumina adsorbent entsha eguqulwe nge-asidi ibonise imiphumela ethembisayo ezifundweni zokususa i-fluoride, kanye nezakhiwo zayo ze-kinetic kanye ne-isotherm ezibonisa ukusebenza kwayo ekususeni i-fluoride emanzini. Lokhu kuphumelela kunikeza inketho engcono yokuqinisekisa ukuphepha kwamanzi okuphuza, ikakhulukazi ezindaweni lapho ukungcola kwe-fluoride ngokweqile kuyinkinga enkulu.

Indlela yokususa i-adsorptive esetshenziswa yi-alumina adsorbent entsha iyisisombululo esingabizi futhi esisebenzayo semiphakathi ebhekene nokungcoliswa kwe-fluoride emithonjeni yayo yamanzi. Ngokungafani nezinye izindlela ezingase zihilele izinqubo eziyinkimbinkimbi nezindleko eziphakeme, ukusetshenziswa kwe-alumina adsorbent eguquliwe nge-acid kunikeza indlela elula nefinyeleleka kalula yokubhekana namazinga e-fluoride emanzini.

Ngaphezu kwalokho, izakhiwo ezithuthukisiwe zokususa i-fluoride ze-adsorbent entsha zinikeza ikhambi eliqhubekayo lokwelashwa kwamanzi, njengoba lingafakwa kalula ezinhlelweni zokwelashwa kwamanzi ezikhona ngaphandle kokuguqulwa okukhulu noma ukutshalwa kwezimali. Lokhu kwenza kube inketho esebenzayo emiphakathini nasezifundeni ezilwela ukulwa nokungcoliswa kwe-fluoride emithonjeni yazo yamanzi.

Ukuthuthukiswa kwe-acid modified alumina adsorbent kumele intuthuko enkulu emkhakheni wokwelashwa kwamanzi kanye nempilo yomphakathi. Ngokunikeza ikhambi eliphumelelayo nelisebenzayo enseleleni ye-fluoride eningi emanzini, lokhu kusungula izinto ezintsha kunamandla okwenza umthelela omuhle empilweni nasenhlalakahleni yemiphakathi emhlabeni jikelele.

Ukuqhubekela phambili, ucwaningo olwengeziwe kanye nentuthuko kule ndawo kuzobaluleka kakhulu ekwenzeni ngcono ukusetshenziswa kwe-adsorbent entsha kanye nokuhlola ukusetshenziswa kwayo okungenzeka ezimweni ezahlukene zokwelashwa kwamanzi. Ngemizamo eqhubekayo kanye nokutshalwa kwezimali kulobu buchwepheshe, kunethemba lokuthi udaba lokungcoliswa kwe-fluoride emanzini lungancishiswa ngempumelelo, kuqinisekiswe ukuthi amanzi okuphuza aphephile futhi ahlanzekile kubo bonke.
