Eminyakeni embalwa edlule, ama-membranes we-graphene oxide asetshenziselwa ukudilizwa kwamanzi kanye nokwehlukana kodayi. Kodwa-ke, ama-membranes anezinhlobonhlobo zezicelo, ezinjengomkhakha wokudla.
Iqembu lokucwaninga elivela enkabeni ye-ShinShu University lifunde ukusetshenziswa kolwelwesi lweGraffide oxide obisini. Lolu hlobo lwe-membrane luvame ukwakha ungqimba olumsulwa olumsulwa (ikhabhoni, i-grafgene oxide membranes yobisi lwamahhala lwe-lactose "kulwelwesi lwe-polymer.).
Vala ulwelwesi lwe-graphene oxide olugcwele i-lactose namanzi; Shiya amafutha, amaprotheni nama-macromolecule obisini.
Ulwelwelwelwelwesi lwe-graphene oxide lunenzuzo yokukhiqiza izingqimba ezibukekayo ze-porous, ngakho-ke ukusebenza kwazo kwe-filltration kungagcinwa kangcono kunama-mempermer we-polymer. Isakhiwo esiyingqayizivele se-chemistry kanye ne-graphene oxide membrane sivumela ukuthuthukisa ukungena kwe-lactose namanzi, ngenkathi kuxosha amanoni, amaprotheni namanye amaminerali. Ngakho-ke, ukuthungwa, ukunambitheka kanye nenani lokudla okunempilo kobisi kungenziwa kugcinwe kangcono uma kuqhathaniswa namafilimu we-polymer.
Ngenxa yokwakheka okuyisisekelo okuhlukile kwesendlalelo se-poruing e-poruing kanye ne-grafgene oxide membrane, ukugcwala kwe-lactose ne-lactose Peresys Flux kuphakeme kakhulu kunalokho okwenziwa ngolwelwesi lwe-nanofilstration. Ngokusebenzisa ulwelwesi lokusekelwa ngosayizi we-pore we-1 μm njengolwelwelwesi lwe-graphene oxide membrane, ukungcoliswa okungenakuphikwa kuyathuthukiswa. Lokhu kuholela ekwakhekeni kwesendlalelo esijabulisayo se-porous, esenza isilinganiso sokutakula esiphakeme sokufutheka kwamanzi ngemuva kokuhlungwa ubisi.
Eqokomisa ukusebenza kwayo okuhle kakhulu okuvelele kanye nokukhetha okuphezulu kwi-lactose, lo msebenzi wokuphayona ukhombisa ukusetshenziswa kwamalungu we-grafgene oxide embonini yezidlo, ikakhulukazi imboni yobisi. Le ndlela igcina amandla amakhulu wokususa ushukela eziphuzweni, ngenkathi egcina ezinye izithako, ngaleyo ndlela zandisa inani lazo lokudla okunempilo.
Izakhiwo eziphakeme ezivuthayo zezixazululo ezicebile eziphilayo (ezifana nobisi) zikwenza futhi kube nokukhetha okuhle kwezinye izinhlelo zokusebenza (njengokulashwa kwamanzi amdaka kanye nezicelo zezokwelapha). Iqembu lihlela ukuqhubeka nokuhlola ukusetshenziswa kwefilimu ye-graphene oxide.
Lo msebenzi ususelwa emiphumeleni yocwaningo lwangaphambilini lweqembu, okungukudalwa kwe-grapgened grafide membranes ("ngempumelelo kanye nodayi nodayi wedayi we-hybrid oxide / i-graphene runbranes") ukuncishiswa kwama-membranis e-nanotechnology. Ulwelwelwesi lukhombisa ukuqina kwamakhemikhali ngokungeza izingqimba ezimbalwa ze-grapheene, ngenkathi kukhombisa ukusebenza kwezindwangu ezinzile ngemuva kwezinsuku ezinhlanu zokusebenza. Ngaphezu kwalokho, indlela yokufakelwa kwe-Spray ithembise kakhulu ngokwemibandela ye-scalability.
