I nā makahiki i hala iho nei, ua hoʻohana nui ʻia nā membrane graphene oxide no ka desalination o ke kai a me ka hoʻokaʻawale wai.Eia nō naʻe, he nui nā ʻano o nā membranes, e like me ka ʻoihana meaʻai.
Ua aʻo kekahi hui noiʻi mai ka Global Aquatic Innovation Center o Shinshu University i ka hoʻohana ʻana i nā membrane graphene oxide i ka waiū.ʻO kēia ʻano membrane e hana maʻamau i kahi papa lepo mānoanoa (carbon, “Grapphene oxide membranes for lactose-free milk” ma nā membrane polymer.).
E pani i ka membrane graphene oxide i hoʻokomo ʻia e ka lactose a me ka wai;waiho i nā momona, nā protein a me nā macromolecules i ka waiū.
Loaʻa i nā membrane graphene oxide ka maikaʻi o ka hana ʻana i nā ʻāpana porous fouling, no laila hiki ke mālama maikaʻi ʻia kā lākou hana kānana ma mua o nā membrane polymer pāʻoihana.ʻO ke kemika kūʻokoʻa a me ke ʻano papa o ka membrane graphene oxide e hiki ai ke hoʻonui i ke komo ʻana o ka lactose a me ka wai, ʻoiai e hoʻihoʻi ana i ka momona, ka protein a me kekahi mau minela.No laila, ʻoi aku ka maikaʻi o ka mālama ʻana i ke ʻano, ka ʻono a me ka waiwai waiwai o ka waiū i hoʻohālikelike ʻia me nā kiʻiʻoniʻoni polymer pāʻoihana.
Ma muli o ke ʻano ʻokoʻa o ke ʻano o ka porous fouling layer a me ka graphene oxide membrane, ʻoi aku ka kiʻekiʻe o ka lactose a me ka lactose permeation flux ma mua o nā membranes nanofiltration kalepa.Ma ka hoʻohana ʻana i kahi membrane kākoʻo me ka nui o ka pore o 1 μm e like me ka membrane graphene oxide, hoʻomaikaʻi ʻia ka hoʻololi ʻole ʻia.Ke alakaʻi nei kēia i ka hoʻokumu ʻana i kahi papa porous fouling, kahi e hiki ai ke kiʻekiʻe kiʻekiʻe o ka hoʻihoʻi hou ʻana o ka kahe wai ma hope o ka kānana ʻana i ka waiū.
Ke hōʻike nei i kāna hana antifouling maikaʻi loa a me ke koho kiʻekiʻe i ka lactose, hōʻike kēia hana paionia i ka hoʻohana ʻana o nā membrane graphene oxide i ka ʻoihana meaʻai, ʻoi aku ka ʻoihana waiu.Mālama kēia ʻano hana i ka mana nui o ka wehe ʻana i ke kō mai nā mea inu, ʻoiai e mālama ana i nā mea ʻē aʻe, no laila e hoʻonui ai i kā lākou meaʻai.
ʻO nā waiwai antifouling kiʻekiʻe o nā mea hoʻonā waiwai waiwai (e like me ka waiū) he koho maikaʻi loa ia no nā noi ʻē aʻe (e like me ka mālama ʻana i ka wai ʻino a me nā noi lapaʻau).Hoʻolālā ka hui e hoʻomau i ka ʻimi ʻana i ka hoʻohana ʻana i ke kiʻi ʻoniʻoni graphene oxide.
Hoʻokumu ʻia kēia hana ma nā hopena noiʻi mua o ka hui, ʻo ia hoʻi ka hana ʻana i nā membrane graphene oxide i hoʻoheheʻe ʻia ("NaCl maikaʻi a me ka hōʻole ʻana o ka graphene oxide/graphene layered membranes hybrid") no ka desalination wai kai i ka nanotechnology kūlohelohe.Hōʻike ka membrane i ke kūpaʻa kemika i hoʻonui ʻia ma ka hoʻohui ʻana i kekahi mau papa o ka graphene, ʻoiai e hōʻike ana i ka hana kānana paʻa ma hope o ʻelima mau lā o ka hana.Eia kekahi, ʻoi aku ka maikaʻi o ke ʻano o ka spray deposition ma ke ʻano o ka scalability.
