Mumakore mashoma apfuura, graphene oxide membranes ainyanya kushandiswa kuburitsa mvura yegungwa uye kupatsanurwa kwedhayi.Nekudaro, membranes ine dzakasiyana siyana dzekushandisa, senge indasitiri yezvekudya.
Chikwata chetsvakiridzo kubva kuGlobal Aquatic Innovation Center yeShinshu University yakadzidza mashandisirwo egraphene oxide membranes mumukaka.Rudzi urwu rwemembrane runowanzo gadzira tsvina yakakora (carbon, "Graphene oxide membranes yemukaka usina lactose" pamapolymer membranes. )
Vhara iyo graphene oxide membrane inopinda nelactose nemvura;siya mafuta, mapuroteni uye macromolecules mumukaka.
Graphene oxide membranes ine mukana wekugadzira porous fouling layers, saka kuita kwavo kusefa kunogona kuchengetedzwa zvirinani pane zvekutengesa polymer membranes.Iyo yakasarudzika chemistry uye akaturikidzana chimiro chegraphene oxide membrane inobvumira kusimudzira kupinda kwelactose nemvura, uku ichidzinga mafuta, mapuroteni uye mamwe mamineral.Naizvozvo, magadzirirwo, kuravira uye kukosha kwekudya kwemukaka kunogona kuchengetedzwa zvirinani kana zvichienzaniswa nemafirimu epolymer ekutengesa.
Nekuda kweiyo yakasarudzika yakaturikidzana dhizaini yeporous fouling layer uye graphene oxide membrane, kuwanda kwelactose uye lactose permeation flux yakakwirira kwazvo kupfuura iyo yekutengesa nanofiltration membranes.Nekushandisa membrane yekutsigira ine saizi yepore ye1 μm se graphene oxide membrane, kusvibiswa kusingadzoreki kunovandudzwa.Izvi zvinotungamira pakuumbwa kweporous fouling layer, iyo inogonesa kudzoreredza mwero wemvura inoyerera mushure mekunge mukaka wapepetwa.
Ichiratidzira kuita kwayo kwakanakisa kwekudzivirira uye kusarudzwa kwepamusoro kune lactose, basa rekupayona iri rinoratidza kushandiswa kwegraphene oxide membranes muindasitiri yezvekudya, kunyanya indasitiri yemukaka.Iyi nzira inoramba iine simba guru rekubvisa shuga kubva muzvinwiwa, nekuchengetedza zvimwe zvigadzirwa, nokudaro kuwedzera kukosha kwavo kwekudya.
Iyo yakakwira antifouling zvimiro zve organic-rich solution (semukaka) inoita kuti ivewo sarudzo yakanaka kune mamwe maapplication (akadai sekurapwa kwemvura yetsvina uye mishonga yekurapa).Boka rinoronga kuenderera mberi nekuongorora mashandisirwo efirimu regraphene oxide.
Iri basa rakavakirwa pane zvakamboitika kutsvagurudzo yeboka, iko kugadzirwa kweakapfapfaidzwa graphene oxide membranes ("Inoshanda NaCl uye kurambwa kwedhayi kweiyo hybrid graphene oxide/graphene layered membranes") yekubvisa mvura yegungwa mune yakasikwa nanotechnology.Iyo membrane inoratidza yakawedzera kugadzikana kwemakemikari nekuwedzera mashoma mashoma egraphene, apo ichiratidza yakagadzikana kusefa kuita mushure memazuva mashanu ekushanda.Uye zvakare, iyo yekupfapfaidza deposition nzira inovimbisa zvakanyanya maererano ne scalability.
