Cov kws tshawb fawb muaj ib puag ncig tus phooj ywg zoo rau cov tshuaj rov qab los ntawm cov thee ya tshauv
Cov kws tshawb nrhiav ntawm cov txheej txheem ntawm Georgia, tau tsim cov txheej txheem yooj yim rau cov dej thee uas siv cov kua tshuaj ionic thiab zam kev tsim kev phom sij. Nyob rau hauv ib daim ntawv luam tawm nyob rau hauv phau ntawv xov xwm ib puag ncig & thev naus laus zis, cov kws tshawb fawb tau hais tias ionic kua tau suav tias yog ib puag ncig benign thiab rov ua dua. Ib qho nyob rau hauv tshwj xeeb, betainium bis (trifluorethylsylsulfonyl) imide lossis [hbet] [tf2n], xaiv tau yaj tsis tshua muaj neeg hlau oxides. Raws li cov kws tshawb fawb, cov kua ionic kuj tsis sib xws rau hauv dej thaum rhuab thiab tom qab ntawd cais ua ob theem thaum txias. Paub txog qhov no, lawv teeb tsa tau sim seb nws puas yuav rub tawm cov khoom uas xav tau tawm ntawm cov thee ya tshauv thiab ua rau muaj kev nyab xeeb, tsim cov txheej txheem uas muaj kev nyab xeeb thiab tsim cov khib nyiab me me. Txhawm rau ua li ntawd, pab pawg pretreated thee Fly tshauv tshauv nrog txoj kev daws teeb meem alkaline thiab qhuav nws. Tom qab ntawd, lawv rhuab tshauv tshem tawm hauv dej nrog [hbet] [tf2n], tsim ib theem. Thaum txias, cov kev daws teeb meem sib cais. Lub ionic kua extracted ntau dua 77% ntawm lub ntiaj teb tsis tshua muaj zog (97%) los ntawm cov tshauv muaj ntau xyoo nyob rau hauv ib lub pas dej cia. Qhov kawg ntawm cov txheej txheem yog mus seev cev tsis tshua muaj kev tsis tshua muaj kua nrog dilute acid. Cov kws tshawb nrhiav kuj tau pom tias ntxiv betaine thaum lub sij hawm leaching nce cov nyiaj tsawg ntawm lub ntiaj teb tsawg-lub ntiaj teb cov khoom siv tau extracted. Scandium, yttrium, kab, cerium, neodymium thiab dysprosium tau nyob ntawm cov lus zoo rov qab. Thaum kawg, pab neeg kuaj cov kua dej ionic los ntawm kev yaug nws nrog cov dej txias kom tshem tawm cov khoom siv txias ntau dhau los ntawm peb lub tsev ntxhua khaub ncaws. "Cov kev daws teeb meem tsawg hauv kev nplua nuj nyob hauv cov ntaub ntawv tsawg, thiab tuaj yeem siv rau cov kws tshawb fawb muaj ntau, thiab tuaj yeem siv cov kws tshawb fawb tau hais tseg," Cov kws tshawb fawb tau hais hauv cov lus qhia tawm. Qhov kev tshawb pom kuj tseem tuaj yeem tseem ceeb rau cov cheeb tsam ua kom tawg, xws li wyoming, uas tab tom kho lawv cov kev lag luam hauv zos txo rau cov pob txha uas tsis ua haujlwm.
