I nā makahiki i hala iho nei, ua hoʻohana nui ʻia nā membrane graphene oxide no ka desalination wai kai a me ka hoʻokaʻawale ʻana i nā kala. Eia nō naʻe, he ākea nā noi o nā membrane, e like me ka ʻoihana meaʻai.
Ua aʻo ʻia e kahi hui noiʻi mai ke Global Aquatic Innovation Center o ke Kulanui ʻo Shinshu ka hoʻohana ʻana o nā membrane graphene oxide i ka waiū. ʻO kēia ʻano membrane ka mea maʻamau e hana i kahi papa lepo mānoanoa (kalapona, "Graphene oxide membranes for lactose-free milk" ma nā membrane polymer.).
E pani i ka membrane graphene oxide i hoʻopili ʻia e ka lactose a me ka wai; e waiho i nā momona, nā protein a me nā macromolecules i loko o ka waiū.
Loaʻa i nā membrane graphene oxide ka pono o ka hana ʻana i nā papa fouling porous, no laila hiki ke mālama maikaʻi ʻia kā lākou hana kānana ma mua o nā membrane polymer kalepa. ʻO ke kemika kū hoʻokahi a me ke ʻano papa o ka membrane graphene oxide e ʻae i ka hoʻoikaika ʻana i ke komo ʻana o ka lactose a me ka wai, me ka pale ʻana i ka momona, ka protein a me kekahi mau minelala. No laila, hiki ke mālama maikaʻi ʻia ke ʻano, ka ʻono a me ka waiwai o ka waiū i hoʻohālikelike ʻia me nā kiʻiʻoniʻoni polymer kalepa.
Ma muli o ke ʻano kū hoʻokahi o ka papa fouling porous a me ka membrane graphene oxide, ʻoi aku ka nui o ka lactose a me ka lactose permeation flux ma mua o nā membrane 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 haumia irreversible. ʻO kēia ke alakaʻi i ka hoʻokumu ʻia ʻana o kahi papa fouling porous, kahi e hiki ai ke hoʻihoʻi hou i ka nui o ka wai ma hope o ka kānana ʻia ʻana o 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 hoʻi ka ʻoihana waiū. Mālama kēia ʻano hana i ka hiki nui o ka wehe ʻana i ke kō mai nā mea inu, me ka mālama ʻana i nā mea ʻē aʻe, no laila e hoʻonui ai i ko lākou waiwai meaʻai.
ʻO nā waiwai antifouling kiʻekiʻe o nā hopena waiwai organik (e like me ka waiū) e lilo ia i koho kūpono no nā noi ʻē aʻe (e like me ka mālama ʻana i ka wai hoʻoneoneo a me nā noi lapaʻau). Hoʻolālā ka hui e hoʻomau i ka ʻimi ʻana i ka hoʻohana ʻana o ka ʻili graphene oxide.
Hoʻokumu ʻia kēia hana ma nā hopena noiʻi mua a ka hui, ʻo ia hoʻi ka hana ʻana o nā membrane graphene oxide i pīpī ʻia ("ʻO ka hōʻole ʻana o NaCl a me ka dye o nā membrane hybrid graphene oxide/graphene layered") no ka desalination wai kai ma ka nanotechnology kūlohelohe. Hōʻike ka membrane i ka paʻa kemika i hoʻonui ʻia ma ka hoʻohui ʻana i kekahi mau papa o ka graphene, me ka hōʻike ʻana i ka hana kānana paʻa ma hope o ʻelima mau lā o ka hana. Eia kekahi, he mea hoʻohiki nui ke ʻano o ka waiho ʻana o ka pīpī ma ke ʻano o ka scalability.
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 hoʻi ka ʻoihana waiū. Mālama kēia ʻano hana i ka hiki nui o ka wehe ʻana i ke kō mai nā mea inu, me ka mālama ʻana i nā mea ʻē aʻe, no laila e hoʻonui ai i ko lākou waiwai meaʻai.
ʻO nā waiwai antifouling kiʻekiʻe o nā hopena waiwai organik (e like me ka waiū) e lilo ia i koho kūpono no nā noi ʻē aʻe (e like me ka mālama ʻana i ka wai hoʻoneoneo a me nā noi lapaʻau). Hoʻolālā ka hui e hoʻomau i ka ʻimi ʻana i ka hoʻohana ʻana o ka ʻili graphene oxide.
Hoʻokumu ʻia kēia hana ma nā hopena noiʻi mua a ka hui, ʻo ia hoʻi ka hana ʻana o nā membrane graphene oxide i pīpī ʻia ("ʻO ka hōʻole ʻana o NaCl a me ka dye o nā membrane hybrid graphene oxide/graphene layered") no ka desalination wai kai ma ka nanotechnology kūlohelohe. Hōʻike ka membrane i ka paʻa kemika i hoʻonui ʻia ma ka hoʻohui ʻana i kekahi mau papa o ka graphene, me ka hōʻike ʻana i ka hana kānana paʻa ma hope o ʻelima mau lā o ka hana. Eia kekahi, he mea hoʻohiki nui ke ʻano o ka waiho ʻana o ka pīpī ma ke ʻano o ka scalability.
