Maitiro akafanana anoita kuti macrusts aumbe mukati metii anogona kubatsira kujekesanickelkusvibiswa kubva mumvura yegungwa, maererano neongororo itsva kubva kuSouth Pacific chitsuwa cheNew Caledonia.
Nickel migodhi ndiyo indasitiri huru yeNew Caledonia, uye chitsuwa chidiki ndechimwe chevagadziri vakuru vesimbi munyika.Asi kusanganiswa kwematombo makuru uye kunaya kwemvura yakawanda kunoreva kuti nickel yakawanda, pamwe nemutobvu nemamwe masimbi, zviri kuguma mumvura dzakapoteredza chitsuwa ichi.Kusvibiswa kwenickel kunogona kukanganisa hutano hwevanhu sezvo huwandu hwayo muhove nehove hunowedzera sezvavanokwidza cheni yechikafu.
Marc Jeannin, injiniya wezvakatipoteredza paYunivhesiti yeLa Rochelle muFrance, uye vaaishanda navo paYunivhesiti yeNew Caledonia muNoumea vakashamisika kana vaigona kushandisa nzira yekudzivirira yecathodic, nzira inoshandiswa kudzora kuparara kwezvivakwa zvesimbi zvomugungwa, kudhonza zvimwe. nickel kubva mumvura..
Kana magetsi asina simba akaiswa kune simbi mumvura yegungwa, zvinoita kuti calcium carbonate uye magnesium hydroxide ibude mumvura uye lime inoisa fomu pamusoro pesimbi.Iyi nzira haina kumbobvira yadzidzwa pamberi pezvakasvibiswa zvesimbi senge nickel, uye vaongorori vakashamisika kana mamwe maion nickel anogona kudonha.
Chikwata ichi chakakandira waya yerata mumugomo wemvura yegungwa yakagadzirwa yakasanganiswa neNiCl2 munyu uye yakamhanyisa magetsi manyoro mairi kwemazuva manomwe.Pakupera kwenguva pfupi iyi, vakawana kuti inosvika 24 muzana yenickel yaivepo pakutanga yaive yakavharirwa mumadhipoziti.
Jeannine anoti iyi inogona kuve yakachipa uye iri nyore nzira yekubvisa iyonickel."Hatigone kubvisa kusvibiswa kwese, asi iyi inogona kunge iri nzira yekuimisa," akadaro.
Migumisiro yacho yakanga isingatarisirwi, sezvo kubviswa kwekusvibiswa kwakanga kusiri pakati pezvinangwa zvepurogiramu yekutanga yekutsvakurudza.Tsvagiridzo huru yaJeannin inotarisisa kugadzira nzira dzekurwisa kukukurwa kwemahombekombe — anoongorora kuti matombo eraimu akavigwa mumambure ewaya pasi pegungwa anogona sei kuita sesimende chaiyo, zvichibatsira kudzikamisa marara pasi pemadhamu kana pamahombekombe ane jecha.
Jeannin akatanga chirongwa muNew Caledonia kuti aone kana mesh ichigona kuteya tsvina yesimbi yakakwana kubatsira kudzidza nhoroondo yenickelkusvibiswa panzvimbo.“Asi apo takaziva kuti taigona kubata chitsama chikuru chenickel, takavamba kufunga pamusoro pezvaigona kushandiswa mumaindasitiri,” anoyeuka kudaro.
Christine Orian, nyanzvi yemakemikari yezvakatipoteredza paYunivhesiti yeBritish Columbia muVancouver, anoti nzira iyi inogona kubvisa kwete nickel chete, asi mamwe masimbi akawanda zvakare."Kunaya kwemvura hakusarudzike," akaudza Chemistry World."Handizivi kana zvingashanda mukubvisa simbi dzine muchetura pasina kubvisa simbi dzinogona kubatsira sesimbi."
Zvisinei, Jeannine haana hanya kuti hurongwa, kana hukaiswa pamwero mukuru, huchabvisa makungwa ezvicherwa zvinokosha.Chete 3% ye calcium uye 0.4% ye magnesium yakabviswa mumvura panguva yekuedza, uye anoti iron iri mugungwa yakakwira zvakakwana kuti irege kuikanganisa zvakanyanya.
Kunyanya, Jeannin akakurudzira kuti hurongwa hwakadaro hunogona kuiswa munzvimbo dzine nickel yakakwira, dzakadai sechiteshi cheNouméa, kuderedza huwandu hunopera mugungwa.Inoda kutariswa kushoma uye inogona kubatanidzwa kune anogonesa simba masosi senge solar panel.Nickel nezvimwe zvinosvibisa zvakavharirwa muchiyero zvinogona kudzoserwa uye kushandiswazve.
Jeannin akati iye nevamwe vake vari kushanda nemakambani muFrance neNew Caledonia kugadzira chirongwa chekuyedza kubatsira kuona kana hurongwa uhu huchigona kufambiswa mukutengesa.
Iyo molecule isingadhuri inopa kuita kwakafanana kune iripo inodhurasimbicatalysts, asi inotarisana nezvinetso zvakakomba maererano nekugadzikana kwayo.
