N'ime afọ ole na ole gara aga, a na-ejikarị ihe mkpuchi graphene oxide eme ihe maka ịsacha mmiri mmiri na nkewa agba. Agbanyeghị, ihe mkpuchi nwere ọtụtụ ojiji, dịka ụlọ ọrụ nri.
Otu ndị nyocha si Global Aquatic Innovation Center nke Mahadum Shinshu amụọla etu esi etinye akpụkpọ graphene oxide n'ime mmiri ara ehi. Ụdị akpụkpọ ahụ a na-etolitekarị unyi dị oke njọ (carbon, "Graphene oxide membranes for lactose-free milk" na akpụkpọ ahụ polymer.).
Mechie akpụkpọ ahụ graphene oxide nke lactose na mmiri jupụtara; hapụ abụba, protein na macromolecules n'ime mmiri ara ehi.
Akpụkpọ anụ oxide graphene nwere uru nke imepụta akwa ntụpọ oghere, yabụ enwere ike idobe arụmọrụ nzacha ha nke ọma karịa akpụkpọ anụ polymer azụmahịa. Kemịkalụ pụrụ iche na nhazi akwa nke akpụkpọ anụ oxide graphene na-enye ohere ime ka lactose na mmiri banye n'ime, ebe ọ na-egbochi abụba, protein na ụfọdụ mineral. Ya mere, enwere ike ichekwa udidi, ụtọ na uru nri nke mmiri ara ehi nke ọma ma e jiri ya tụnyere ihe nkiri polymer azụmahịa.
N'ihi nhazi pụrụ iche nke oyi akwa porous fouling na graphene oxide membrane, oke lactose na lactose permeation flux dị elu karịa nke nanofiltration membranes azụmahịa. Site na iji ihe nkwado nwere obere oghere nha 1 μm dị ka graphene oxide membrane, mmetọ a na-apụghị ịgbagha agbagha na-aka mma. Nke a na-eduga n'ịmepụta obere oghere porous fouling, nke na-eme ka mmiri gbakee ngwa ngwa mgbe a sachara mmiri ara ehi ahụ.
N'ịkọwapụta arụmọrụ ya dị mma nke igbochi ntụpọ na nhọrọ dị elu maka lactose, ọrụ mbụ a na-egosi itinye akpụkpọ anụ graphene oxide n'ọrụ n'ụlọ ọrụ nri, ọkachasị ụlọ ọrụ mmiri ara ehi.

Ọrụ a dabere na nsonaazụ nyocha nke otu ahụ mere na mbụ, ya bụ imepụta akpụkpọ anụ graphene oxide a gbanyere agba (“NaCl dị irè na ịjụ agba nke akpụkpọ anụ graphene oxide/graphene a gbanyere agba) maka ịsacha mmiri mmiri n'ime teknụzụ nano. Akpụkpọ ahụ na-egosi nkwụsi ike kemịkalụ ka mma site na ịgbakwunye obere oyi akwa graphene, ebe ọ na-egosipụta arụmọrụ nzacha kwụsiri ike mgbe ụbọchị ise nke ọrụ gasịrị. Na mgbakwunye, usoro itinye ihe n'ime mmiri na-ekwe nkwa nke ukwuu n'ihe gbasara nha nha.
