Mumakore mashoma apfuura, ma membrane e graphene oxide ave achinyanya kushandiswa kubvisa munyu mumvura yegungwa uye kupatsanura dhayi. Zvisinei, ma membrane ane mashandisirwo akasiyana-siyana, akadai seindasitiri yechikafu.
Chikwata chekutsvagisa kubva kuGlobal Aquatic Innovation Center yeShinshu University chakadzidza nezvekushandiswa kwe graphene oxide membranes mumukaka. Rudzi urwu rwe membrane runowanzoita denderedzwa revhu (carbon, "Graphene oxide membranes for lactose-free milk" pa polymer membranes.).
Vhara membrane ye graphene oxide yakazadzwa ne lactose nemvura; siya mafuta, mapuroteni uye macromolecules mumukaka.
Ma membrane eGraphene oxide ane mukana wekugadzira ma layer ane maburi, saka mashandiro awo ekusefa anogona kuchengetedzwa zviri nani pane ma membrane e polymer ekutengesa. Kemikari yakasiyana uye chimiro chakaiswa ma layer e membrane yeGraphene oxide zvinobvumira kuwedzera kupinda kwe lactose nemvura, ukuwo zvichidzinga mafuta, mapuroteni nezvimwe zvicherwa. Nokudaro, magadzirirwo, kunaka uye kukosha kwekudya kwemukaka zvinogona kuchengetedzwa zviri nani zvichienzaniswa nemafirimu e polymer ekutengesa.
Nekuda kwechimiro chakasiyana chechikamu cheporous fouling layer ne graphene oxide membrane, huwandu hwe lactose ne lactose permeation flux hwakakwira zvakanyanya kupfuura hwe commercial nanofiltration membranes. Nekushandisa support membrane ine pore size ye 1 μm se graphene oxide membrane, kusvibiswa kusingadzoreki kunovandudzwa. Izvi zvinotungamira pakuumbwa kwechikamu cheporous fouling layer, izvo zvinoita kuti mvura idzoke nekukurumidza mushure mekunge mukaka wasefa.
Ichiratidza kushanda kwayo kwakanaka kwekudzivirira kusvibiswa uye kusarudza kwakanyanya kwe lactose, basa iri rekutanga rinoratidza kushandiswa kwe graphene oxide membranes muindasitiri yezvikafu, kunyanya indasitiri yemukaka. Nzira iyi inoramba iine mukana mukuru wekubvisa shuga kubva muzvinwiwa, ukuwo ichichengetedza zvimwe zvinoshandiswa, nokudaro ichiwedzera kukosha kwayo kwekudya.
Hunhu hwakawanda hwezvinhu zvakapfuma mu organic (senge mukaka) hunodzivirira kusvibiswa kunoita kuti ive sarudzo yakanaka kune zvimwe zvinoshandiswa (senge kurapwa nemvura yakasviba uye kushandiswa kwekurapa). Boka iri rinoronga kuramba richitsvaga kushandiswa kwe graphene oxide film.
Basa iri rakavakirwa pamhedzisiro yekutsvagisa kweboka, kureva kugadzirwa kwe graphene oxide membranes dzakapfapfaidzwa ("NaCl inoshanda uye kurambwa kwedhayi kwe hybrid graphene oxide/graphene layered membranes") yekubvisa munyu mumvura yegungwa mu nanotechnology yechisikigo. Kamudzira kanoratidza kugadzikana kwemakemikari nekuwedzera zvidimbu zvishoma zve graphene, ukuwo kachiratidza kushanda kwakagadzikana kwekusefa mushure memazuva mashanu ekushanda. Pamusoro pezvo, nzira yekuisa spray ine tariro huru maererano nekukwanisa kukura.
