Kule minyaka imbalwa idlulileyo, i-meraphene i-membrane isetyenziselwa ikakhulu kumanzi aselwandle amanzi kunye nokuqhawuka kwedayi. Nangona kunjalo, i-membrane inoluhlu olubanzi lwezicelo, ezinjengeshishini lokutya.
Iqela lophando elivela kwiZiko eliPhezulu leHlabathi le-Global Aquity leYunivesithi yaseShinshi lifunde isicelo se-Graphene Oxide ebisini. Olu hlobo lwe-membrane luhlala luyingcangcazela emdaka (ikharbon, "i-meraphene dembranes ye-lactose-free" kwi-polymer memmdranes.).
Vala i-meraphene dembrane ye-oxide idlwengulwe liLactose namanzi; Shenxisa amanqatha, iiproteni kunye ne-macromolecules ebisini.
I-Graphene I-Membrane inenzuzo yokuvelisa izalethi ezingcolileyo, ukuze i-fildioding yazo inokugcinwa ngcono kune-melymer ye-polymer yorhwebo. I-chemistry eyahlukileyo kunye nesakhiwo se-membrane esixineneyo sivumela ukukhulisa ukungena kwe-lactose kunye namanzi, ngelixa bephinda amanqatha, protein kunye neeminerali. Ke ngoko, isigaba, incasa kunye nexabiso lesondlo kwaye ixabiso lesondlo lingagcinwa ngcono xa lithelekiswa neefilimu zePolymer zePolymer.
Ngenxa yobume obukhethekileyo be-face of the qual ye-ping kunye ne-meraphene oxide, uxinzelelo lwe-lactose kunye ne-Lactose i-facment falls iphakame kakhulu kune-nanofnes ethengisayo. Ngokusebenzisa i-membrane yenkxaso ngobukhulu be-1 μm njenge-membrane ye-oxide, ungcoliseko olungenakutshitshiswa luphuculwe. Oku kukhokelela ekusekweni kwesakhelo esingcolileyo, oko kwenza ukuba inqanaba lokufumana amanzi eliphakamileyo le-fluax emva kokuba ubisi luhlulwe.
Ukuqaqambisa kwayo yokungaphumeleli i-actouling kunye nokukhetho okuphezulu kweLactose, lo msebenzi wobuvulindlela ubonakalisa ukusetyenziswa kwe-memphene dembranes kumzi-mveliso wokutya, ngakumbi ishishini lobisi. Le ndlela igcina amandla amakhulu okususa iswekile kwiziselo, ngelixa ugcina ezinye izithako, ngaloo ndlela enyusa ixabiso labo lesondlo.
IiPropathi eziPhakamileyo zeZisombululo eziPhezulu zezinto eziPhezulu (ezinje ngobisi) zenza lukhetho olufanelekileyo lwezinye iinkqubo (njengokunyanga kwamanzi amdaka kunye nezicelo zonyango). Iqela liceba ukuqhubeka nokuphonononga ukusetyenziswa kwefilimu ye-diaphene oxcide.
Lo msebenzi usekwe kwiziphumo zophando zangaphambili zeqela, oko kukuthi, indalo ye-subragune ye-daphene ("i-dacl kunye ne-dayin ye-dando oxide / i-Graphene ye-Grapheness") kwi-Eanotechnology yendalo ye-Nanotechnology. I-membrane ibonisa uzinzo lwekhemikhali ekongezayo kwii-Grainel Graphene, ngelixa ibonisa ukusebenza okuzinzileyo okuzinzileyo emva kweentsuku ezintlanu zomsebenzi. Ukongeza, indlela yokukhuphela i-Spray ithembisa kakhulu ngokwemigaqo yokunganyamezelani.
