Asayansi apanga njira yosamalira zachilengedwe yobwezeretsanso REE ku phulusa la ntchentche za malasha

Ofufuza ku Georgia Institute of Technology, apanga njira yosavuta yopezera zinthu zapadziko lapansi zomwe sizipezeka kuchokera ku phulusa la ntchentche za malasha pogwiritsa ntchito madzi a ayoni komanso kupewa zinthu zowopsa.
Mu pepala lofalitsidwa mu nyuzipepala ya Environmental Science & Technology, asayansi akufotokoza kuti zakumwa za ionic zimaonedwa kuti ndizosavulaza zachilengedwe ndipo zimatha kugwiritsidwanso ntchito.Imodzi makamaka, betainium bis(trifluoromethylsulfonyl)imide kapena [Hbet][Tf2N], imasungunula ma oxide osowa padziko lapansi pamwamba pa zitsulo zina.
Malinga ndi asayansi, madzi a ionic amasungunukanso m'madzi mwapadera akatenthedwa kenako amagawanika m'magawo awiri akakhazikika.Podziwa izi, adakhazikitsa kuti ayese ngati angakoke bwino komanso mwamakonda zinthu zomwe akufuna kuchokera ku phulusa la ntchentche za malasha komanso ngati zitha kutsukidwa bwino, ndikupanga njira yomwe ili yotetezeka komanso yosataya zinyalala.
Kuti achite izi, gululo lidawotcha phulusa la ntchentche zamakala ndi mankhwala amchere ndikuumitsa.Kenako, adatenthetsa phulusa loyimitsidwa m'madzi ndi [Hbet][Tf2N], ndikupanga gawo limodzi.Pamene utakhazikika, zothetsera analekanitsidwa.Madzi a ionic adatulutsa zinthu zopitilira 77% zapadziko lapansi kuchokera kuzinthu zatsopano, ndipo adapezanso kuchuluka kwambiri (97%) kuchokera kuphulusa losasunthika lomwe lakhala zaka zambiri m'dziwe losungiramo.Gawo lomaliza la ndondomekoyi linali kuvula zinthu zapadziko lapansi zomwe sizipezeka mu madzi a ayoni ndi asidi osungunuka.
Ofufuzawo adapezanso kuti kuwonjezera betaine panthawi ya leaching kumawonjezera kuchuluka kwa zinthu zapadziko lapansi zomwe zimachotsedwa.
Scandium, yttrium, lanthanum, cerium, neodymium ndi dysprosium zinali zina mwa zinthu zomwe zidachira.
Pomaliza, gululo linayesa kugwiritsiranso ntchito kwa madzi a ionic pomutsuka ndi madzi ozizira kuti achotse asidi ochulukirapo, osapeza kusintha kwake pakutulutsa kwake kudzera m'mizere itatu yoyeretsa.
"Njira yochepetsera zinyalalayi imapanga yankho lolemera mu zinthu zapadziko lapansi zosowa, zokhala ndi zonyansa zochepa, ndipo zitha kugwiritsidwa ntchito kukonzanso zinthu zamtengo wapatali kuchokera ku phulusa lambiri la ntchentche za malasha zomwe zimasungidwa m'mayiwe osungira," adatero asayansi m'mawu ofalitsa nkhani.
Zomwe zapezazi zitha kukhala zofunikiranso kumadera omwe amapanga malasha, monga Wyoming, omwe akufuna kubwezeretsanso makampani awo akumaloko poyang'ana kuchepa kwa kufunikira kwamafuta.
