Maitiro anoita kuti macrusts aumbe mukati metiipoti anogonawo kubatsira kuchenesa kusvibiswa kwenickel kubva mumvura yegungwa, maererano neongororo itsva kubva kuSouth Pacific chitsuwa cheNew Caledonia.
       Nickelmigodhi ndiyo indasitiri huru muNew Caledonia;chitsuwa chidiki ndechimwe chevagadziri vakuru vesimbi pasi rose.Asi musanganiswa wemakomba mahombe akazaruka uye kunaya kwemvura zhinji kwakonzera kuwanda kwe nickel, lead nemamwe masimbi anoguma apinda mumvura dzakapoteredza zvitsuwa.Kusvibiswa kwenickel kunogona kukanganisa hutano hwevanhu sezvo huwandu hwayo muhove nehove hunowedzera paunenge uchikwidza cheni yechikafu.
Marc Jeannin, injiniya wezvakatipoteredza paYunivhesiti yeLa Rochelle muFrance, uye vaaishanda navo paYunivhesiti yeNew Caledonia kuNouméa vainetseka kana vaigona kushandisa nzira yekudzivirira kathodic, nzira inoshandiswa kurwisa kuparara kwezvivakwa zvesimbi zvomugungwa, kuti vawane zvimwe. nickel kubva mumvura.
Kana magetsi asina simba akaiswa kune simbi mumvura yegungwa, calcium carbonate uye magnesium hydroxide inodonha kubva mumvura uye inoita lime deposits pamusoro pesimbi.Maitiro aya haana kumbobvira adzidzwa pamberi pesimbi yetsvina senge nickel, uye vaongorori vakashamisika kana mamwe nickel ions angangovharirwawo mumvura inonaya.
Chikwata ichi chakakandira waya yerata mumugomo wemvura yegungwa yekugadzira iyo yaive yawedzerwa munyu weNiCl2 kwairi ndokumhanyisa magetsi manyoro kwemazuva manomwe.Mushure menguva pfupi iyi, vakaona kuti inosvika 24 muzana yenickel yaivepo pakutanga yaive yakavharirwa mumadhipoziti.
Jannen anoti inogona kuve isingadhure uye iri nyore nzira yekubvisanickelkusvibiswa."Hatigoni kubvisa zvachose kusvibiswa, asi iyo inogona kuva imwe nzira yekuimisa," akadaro.
Mhedzisiro yacho yaive neimwe nzira, sezvo kubviswa kwekusvibiswa kwaisava chimwe chezvinangwa zvechirongwa chetsvakiridzo chepakutanga.Tsvagiridzo huru yaJanine yakanangana nekugadzira nzira dzekurwisa kukukurwa kwemahombekombe: anodzidza kuti madhipoziti e lime akavigwa muwaya mesh pasi pegungwa anogona kuita senge simende yechisikigo, achibatsira kudzikamisa madhipoziti pasi pedhayi kana pamahombekombe ane jecha.
Jannin akatanga chirongwa muNew Caledonia kuona kana network ichikwanisa kubata tsvina yesimbi yakakwana kubatsira kudzidza nhoroondo yesaiti yekusvibiswa nickel.“Asi apo takaziva kuti taigona kutora mavhoriyamu makuru enickel, takavamba kufunga pamusoro pezvingabvira zvekushandisa mumaindasitiri,” anoyeuka kudaro.
Nzira iyi haibvisi nickel chete, asi mamwe masimbi akawanda zvakare, anodaro nyanzvi yekemisitiri yezvakatipoteredza Christine Orians weYunivhesiti yeBritish Columbia muVancouver."Kunaya kwemvura hakusarudzike," akaudza Chemistry World."Handizive kana zvichizoshanda pakubvisa simbi dzine muchetura pasina kubvisa simbi dzinogona kubatsira sesimbi."
Jeanning, zvisinei, haina hanya kuti hurongwa, kana hukaiswa pamwero mukuru, huchabvisa zvakakosha zvicherwa kubva mugungwa.Mukuedza kwakabvisa chete 3 muzana ye calcium uye 0.4 muzana ye magnesium kubva mumvura, iyo iron iri mugungwa yakakwira zvakakwana kuti isave nemhedzisiro yakawanda, akadaro.
Kunyanya, Jeannin akakurudzira kuti hurongwa hwakadaro hunogona kuiswa munzvimbo dzakakwirira dzekurasikirwa kwenickel dzakadai sechiteshi cheNoumea kubatsira kuderedza kuwanda kwenickelkuguma mugungwa.Izvo hazvidi kutonga kwakawanda uye zvinogona kubatanidzwa kune renewable simba masosi akadai solar panels.Nickel nezvimwe zvinosvibisa zvakabatwa muchiyero zvinogona kudzoserwa uye kushandiswazve.
Jeanning akati iye nevamwe vake vari kushanda nemakambani ari kuFrance neNew Caledonia kugadzira chirongwa chekuyedza kubatsira kuona kana hurongwa uhu huchigona kuiswa pamwero weindasitiri.
