Ososayensi bathuthukisa indlela enobungani bemvelo yokuthola kabusha i-Ree kusuka ku-Coal Fly Ash
Abaphenyi eGeorgia Institute of Technology, bathuthukise indlela elula yokubuyisa izinto zomhlaba ezingandile kusuka ku-Coal Fly Ash usebenzisa i-Ionic Liquid futhi ugweme izinto eziyingozi. Ephepheni elishicilelwe ejeni lezemvelo Science & Technology, ososayensi bachaza ukuthi ama-Ionic ketshezi abhekwa njengemvelo yemvelo futhi ayasebenza kabusha. Enye, i-betainium bis (TrifluoromethsulFonyl) iMide noma [Hbet] [TF2N], ikhethe inciphisa okungajwayelekile - ama-oxide e-Earth Earth ngaphezu kwamanye ama-oxides wensimbi. Ngokusho kososayensi, uketshezi lwe-ionic luhlakazeke ngokuhlukile emanzini lapho lifudumala bese lihlukanisa izigaba ezimbili lapho zipholile. Ukwazi lokhu, bahlela ukuvivinya uma bengakwazi ukudonsa kahle izinto ezifunwayo ngaphandle komlotha wamalahle amalahle nokuthi ngabe zihlanzwa ngempumelelo, zakha inqubo ephephile futhi yakhiqiza imfucuza encane. Ukuze wenze njalo, iqembu lihlehliswe amalahle amalahle umlotha ngesisombululo se-alkali futhi somisa. Ngemuva kwalokho, bashisa umlotha bamiswe emanzini nge [hbet] [TF2n], bedala isigaba esisodwa. Lapho kupholile, izixazululo zahlukaniswa. Uketshezi lwe-Ionic ukhiphe ngaphezu kwama-77% ezinto ezingaphezu kwama-77 zomhlaba ezivela ezintweni ezintsha, futhi walulama amaphesenti aphezulu (97%) kusuka kumlotha we-simo wachitha echibini lokugcina. Ingxenye yokugcina yenqubo kwakuwukugxuma izinto ezingandile ezingafani namhlaba kusuka ku-ionic ketshezi nge-dilute acid. Abaphenyi baphinde bathola ukuthi ukwengeza i-betaine ngesikhathi sesinyathelo sokufuya kwandise inani lezinto ezivamile zomhlaba ezikhishwe. I-Scandium, i-YTTRIUM, iLanthanum, i-CERUIM, iNeodymium ne-dysprosium yayiphakathi kwezinto ezitholile. Finally, the team tested the ionic liquid's reusability by rinsing it with cold water to remove excess acid, finding no change in its extraction efficiency through three leaching-cleaning cycles. "Le ndlela ephansi ikhiqiza isisombululo esicebile ezindaweni ezingavamile emhlabeni, ngokungcola okulinganiselwe, futhi ingasetshenziselwa ukuphinda usebenzise izinto eziyigugu ezinokuchichima kwamachibi okugcina," ososayensi bathi esitatimendeni semithombo yezindaba. Okutholakele nakho kungaba nzima kakhulu ezifundeni ezikhiqiza amalahle, ezinjengeWyoming, ezifuna ukuqinisa kabusha imboni yazo yasekhaya ebusweni bokuncipha kwesidingo samafutha amancane.
