I ngā tau kua taha ake nei, ko ngā kiriuhi waikura graphene te nuinga o te wā e whakamahia ana mō te tango tote i te wai moana me te wehewehe tae. Heoi anō, he whānuitia ngā whakamahinga o ngā kiriuhi, pērā i te umanga kai.
Kua rangahauhia e tētahi rōpū rangahau mai i te Global Aquatic Innovation Center o Te Whare Wānanga o Shinshu te whakamahinga o ngā kiriuhi graphene oxide i roto i te miraka. Ko tēnei momo kiriuhi ka hanga i tētahi paparanga paru matotoru (waro, "Ngā kiriuhi graphene oxide mō te miraka kore-lactose" i runga i ngā kiriuhi polymer).
Katia te kiriuhi waikura graphene kua uru ki te lactose me te wai; waiho ngā ngako, ngā pūmua me ngā macromolecules i roto i te miraka.
He painga tō ngā kiriuhi waikura graphene ki te whakaputa i ngā paparanga paru porous, nō reira ka taea te pupuri pai ake i tā rātou mahi tātari i ngā kiriuhi polymer arumoni. Mā te matū ahurei me te hanganga paparanga o te kiriuhi waikura graphene ka taea te whakarei ake i te urunga o te lactose me te wai, me te pana atu hoki i te ngako, te pūmua me ētahi kohuke. Nō reira, ka taea te tiaki pai ake i te kakano, te reka me te uara kai o te miraka ki te whakaritea ki ngā kiriata polymer arumoni.
Nā te hanganga ahurei o te paparanga paru porowhita me te kiriuhi graphene oxide, he nui ake te kukū o te lactose me te rerenga uruhanga lactose i ērā o ngā kiriuhi nanofiltration arumoni. Mā te whakamahi i te kiriuhi tautoko he 1 μm te rahi o te pore hei kiriuhi graphene oxide, ka pai ake te poke kore e taea te whakakore. Ka hua ake tēnei i te hanganga o te paparanga paru porowhita, ka taea ai te tere whakaora ake o te rerenga wai i muri i te tātaritanga o te miraka.
E whakaatu ana tēnei mahi matua i te whakamahinga o ngā kiriuhi graphene oxide i roto i te umanga kai, inā koa te umanga miraka, me te whakaatu i tōna mahi ārai-parauri me tōna kaha ki te whiriwhiri i te lactose, ā, e whakaatu ana tēnei mahi matua i te whakamahinga o ngā kiriuhi graphene oxide i roto i te umanga kai, inā koa te umanga miraka. Ka mau tonu i tēnei tikanga te kaha nui ki te tango i te huka mai i ngā inu, me te pupuri tonu i ētahi atu kai, ā, ka whakanui ake i te uara kai.
Nā te kaha o ngā āhuatanga ārai-para o ngā otinga whai rawa i te rauropi (pērā i te miraka) he mea pai hoki mō ētahi atu whakamahinga (pērā i te maimoatanga waipara me ngā whakamahinga hauora). Kei te whakamahere te rōpū ki te tūhura tonu i te whakamahinga o te kiriata graphene oxide.
I ahu mai tēnei mahi i ngā hua rangahau o mua a te rōpū, arā, ko te hanganga o ngā kiriuhi waikura graphene i rehuhia ("Te whakakorenga NaCl me te tae whai hua o ngā kiriuhi paparanga graphene waikura/graphene ranu") mō te tango tote wai moana i roto i te hangarau nano tūturu. E whakaatu ana te kiriuhi i te pumau matū kua whakarei ake mā te tāpiri i ētahi paparanga graphene, me te whakaatu i te mahi tātari pumau i muri i ngā rā e rima o te mahi. Hei tāpiri, he tino whai hua te tikanga whakatakoto rehu i runga i te kaha ki te whakawhanui.
