Njira yomwe imapangitsa kuti makutu apangidwe mkati mwa tiyi angathandizenso kuyeretsa madzi a m'nyanja ndi nickel, malinga ndi kafukufuku watsopano wochokera ku chilumba cha South Pacific cha New Caledonia.
       Nickelmigodi ndi bizinesi yayikulu ku New Caledonia;chilumba chaching'onocho ndi chimodzi mwazinthu zazikulu kwambiri zopanga zitsulo padziko lonse lapansi.Koma kuphatikiza kwa maenje akuluakulu otseguka ndi mvula yamphamvu kwachititsa kuti faifi wochuluka, lead ndi zitsulo zina zithere m’madzi ozungulira zisumbuzi.Kuipitsa kwa nickel kumatha kuwononga thanzi la munthu chifukwa kuchuluka kwake mu nsomba ndi nkhono kumawonjezeka pamene mukukwera m'zakudya.
Marc Jeannin, katswiri wa zachilengedwe payunivesite ya La Rochelle ku France, ndi anzake a payunivesite ya New Caledonia ku Nouméa ankadabwa ngati angagwiritse ntchito njira yoteteza zitsulo za m’madzi, yomwe ndi njira yothana ndi dzimbiri ya zitsulo za m’madzi. nickel kuchokera m'madzi.
Mphamvu yamagetsi yofooka ikagwiritsidwa ntchito pazitsulo m'madzi a m'nyanja, calcium carbonate ndi magnesium hydroxide zimatuluka m'madzi ndikupanga ma depositi a laimu pamwamba pa chitsulocho.Izi sizinayambe zaphunziridwapo pamaso pa zonyansa zachitsulo monga faifi tambala, ndipo ofufuzawo ankadabwa ngati ma ion ena a nickel angakhalenso atatsekeredwa mumadzi.
Gululo linaponyera waya wachitsulo mumtsuko wamadzi ochita kupanga omwe adawonjezedwamo mchere wa NiCl2 ndikuyendetsa mphamvu yamagetsi pang'ono kwa masiku asanu ndi awiri.Patapita nthawi yochepayi, anapeza kuti pafupifupi 24 peresenti ya faifi tambala yomwe inalipo poyamba inali itatsekeredwa m’madipoziti.
Jannen akuti ikhoza kukhala njira yotsika mtengo komanso yosavuta yochotseranickelkuipitsidwa."Sitingathe kuthetseratu kuipitsa, koma imeneyo ikhoza kukhala njira imodzi yochepetsera," adatero.
Zotsatira zake zinali zongochitika mwachisawawa, popeza kuthetseratu kuipitsa sikunali cholinga chimodzi cha pulogalamu yofufuza yoyambirira.Kufufuza kwakukulu kwa Janine kumayang'ana pakupanga njira zothanirana ndi kukokoloka kwa m'mphepete mwa nyanja: amaphunzira momwe ma depositi a laimu okwiriridwa mu mawaya pansi pa nyanja atha kukhala ngati simenti yachilengedwe, kuthandiza kukhazikika kwa ma depositi pansi pa dykes kapena magombe amchenga.
Jannin adayambitsa pulojekiti ku New Caledonia kuti adziwe ngati maukonde angagwire kuipitsidwa kwachitsulo kokwanira kuti athandizire kuphunzira mbiri ya malowa yakuwonongeka kwa faifi tambala.“Koma titazindikira kuti titha kujambula faifi tambala wambiri, tinayamba kuganizira za ntchito za mafakitale,” akukumbukira motero.
Njirayi sikuti imangochotsa faifi tambala, komanso zitsulo zina zambiri, akutero katswiri wazachilengedwe Christine Orians wa pa yunivesite ya British Columbia ku Vancouver."Kukhala ndi mpweya sikusankha," adauza Chemistry World."Sindikudziwa ngati zingathandize kuchotsa zitsulo zapoizoni zokwanira popanda kuchotsa zitsulo zomwe zingakhale zothandiza ngati chitsulo."
Jeanning, komabe, alibe nkhawa kuti dongosololi, ngati litayikidwa pamlingo waukulu, lidzachotsa mchere wofunikira m'nyanja.Muzoyesera zomwe zinachotsa 3 peresenti ya calcium ndi 0,4 peresenti ya magnesium m'madzi, zitsulo zachitsulo m'nyanja zimakhala zokwanira kuti zisakhale ndi zotsatira zambiri, adatero.
Mwachindunji, Jeannin adanenanso kuti makina oterowo atha kutumizidwa kumalo otayika kwambiri monga doko la Noumea kuti athandize kuchepetsanickelkukathera m’nyanja.Sizikufuna kulamulira kwambiri ndipo zimatha kulumikizidwa ndi mphamvu zongowonjezwdwa monga ma solar panels.Nickel ndi zowononga zina zomwe zimagwidwa pamlingo zimatha kubwezeredwa ndikubwezerezedwanso.
Jeanning adati iye ndi anzake akugwira ntchito ndi makampani ku France ndi New Caledonia kuti apange pulojekiti yoyendetsa ndege kuti adziwe ngati dongosololi lingagwiritsidwe ntchito pamakampani.
