I-alumina evuliwe

Impumelelo kubuchwepheshe be-defluoridation ifinyelelwe ngokuthuthukiswa kwe-alumina adsorbent enoveli eyi-asidi. Lesi sidakamizwa esisha se-adsorbent sibonise izakhiwo ezithuthukisiwe zokuqeda i-fluorid emanzini angaphansi nangaphezulu, okubalulekile ekubhekaneni namazinga ayingozi okungcoliswa kwe-fluoride abeka ingozi enkulu empilweni yabantu.

Ukweqisa kwe-fluoride emanzini okuphuza kuye kwaxhunyaniswa nohlu lwezinkinga zezempilo, okuhlanganisa i-fluorosis yamazinyo nohlaka lwamathambo, nezinye izimo zempilo ezinzima. Njengoba izindlela zendabuko zokuhlanza amanzi zibonakala zingasebenzi ekukhipheni i-fluoride emanzini, ukwakhiwa kwe-adsorbent ephumelelayo kunikeza ithemba elisha ekubhekaneni nale nkinga ecindezelayo.

I-alumina adsorbent eshintshiwe ye-asidi ibonise imiphumela ethembisayo ezifundweni ze-defluoridation, nezici zayo ze-kinetic ne-isotherm ezibonisa ukusebenza kahle kwayo ekukhipheni i-fluoride emanzini. Lokhu kuphumelela kunikeza inketho engcono yokuqinisekisa ukuphepha kwamanzi okuphuza, ikakhulukazi ezindaweni lapho ukungcoliswa kwe-fluoride kuyinkinga enkulu.

Indlela yokukhipha i-adsorptive esetshenziswa i-alumina adsorbent entsha iyisixazululo esingabizi kakhulu nesisebenzayo semiphakathi ebhekene nokungcoliswa kwe-fluoride emithonjeni yayo yamanzi. Ngokungafani nezinye izindlela ezingase zibandakanye izinqubo eziyinkimbinkimbi kanye nezindleko eziphezulu, ukusetshenziswa kwe-alumina adsorbent eguquliwe ye-asidi kunikeza indlela elula futhi efinyeleleka kakhulu yokubhekana namazinga e-fluoride emanzini.

Ngaphezu kwalokho, izici ezithuthukisiwe ze-defluoridation ye-adsorbent yenoveli zinikeza isixazululo esimeme sokuhlanzwa kwamanzi, njengoba singahlanganiswa kalula nezinhlelo ezikhona zokuhlanza amanzi ngaphandle kwezinguquko ezibalulekile noma ukutshalwa kwezimali. Lokhu kwenza kube inketho esebenzayo emiphakathini nasezifundeni ezidonsa kanzima ukulwa nokungcoliswa kwe-fluoride emithonjeni yazo yamanzi.

Ukuthuthukiswa kwe-alumina adsorbent elungiswe nge-asidi kumelela inqubekelaphambili ebalulekile emkhakheni wokwelashwa kwamanzi kanye nempilo yomphakathi. Ngokunikeza isixazululo esisebenzayo nesisebenzayo enseleleni ye-fluoride eyeqile emanzini, lokhu okusha kunamandla okwenza umthelela omuhle ezimpilweni nasenhlalakahleni yemiphakathi emhlabeni jikelele.

Ukuqhubekela phambili, ucwaningo olwengeziwe kanye nentuthuko kule ndawo izobaluleka ekwandiseni ukusetshenziswa kwe-adsorbent yenoveli kanye nokuhlola okungenzeka isetshenziswe ezimeni ezahlukene zokwelashwa kwamanzi. Ngokuqhubeka kwemizamo kanye nokutshalwa kwezimali kulobu buchwepheshe, kwethenjwa ukuthi udaba lokungcoliswa kwe-fluoride emanzini lungancishiswa ngempumelelo, kuqinisekiswe amanzi okuphuza aphephile nahlanzekile kubo bonke.
