Inzira imwe itera igikonjo gukora imbere yicyayi gishobora gufasha gusibanikelkwanduza amazi yo mu nyanja, nk'uko ubushakashatsi bushya bwaturutse ku kirwa cya Pasifika y'Amajyepfo ya New Caledoniya.
Ubucukuzi bwa Nickel n’inganda zikomeye za New Caledoniya, kandi ikirwa gito ni kimwe mu bitanga ibyuma byinshi ku isi.Ariko guhuza kariyeri nini n'imvura nyinshi bivuze ko nikel nyinshi, kimwe na gurş hamwe nibindi byuma, birangirira mumazi akikije ikirwa.Umwanda wa Nickel urashobora kubangamira ubuzima bwabantu kuko kwibanda ku mafi n’ibishishwa byiyongera uko bizamuka mu biribwa.
Marc Jeannin, injeniyeri w’ibidukikije muri kaminuza ya La Rochelle mu Bufaransa, na bagenzi be bo muri kaminuza ya New Caledoniya i Noumea bibajije niba bashobora gukoresha inzira yo gukingira gatolika, ubwo buryo bukoreshwa mu kugenzura ruswa y’ibyuma byo mu nyanja, kugira ngo bakurure bamwe nikel mu mazi..
Iyo umuyagankuba udakomeye ushyizwe mubyuma mumazi yinyanja, bitera calcium karubone na hydroxide ya magnesium igwa mumazi kandi imyanda ya lime iba hejuru yicyuma.Ubu buryo ntabwo bwigeze bwigwa imbere y’ibyuma byangiza nka nikel, kandi abashakashatsi bibajije niba zimwe muri ion za nikel zishobora kugwa.
Itsinda ryataye insinga z'icyuma mu ndobo y'amazi yo mu nyanja avanze n'umunyu wa NiCl2 maze ikoresha amashanyarazi yoroheje muri yo iminsi irindwi.Mu gihe gito kirangiye, basanze hafi 24 ku ijana bya nikel yari isanzweho bari bafatiwe mu bubiko.
Jeannine avuga ko iyi ishobora kuba inzira ihendutse kandi yoroshye yo kwikuramonikel.Ati: "Ntidushobora gukuraho umwanda wose, ariko iyi ishobora kuba inzira yo kuyigabanya."
Ibisubizo ntibyari byitezwe, kubera ko kurandura umwanda bitari mu ntego za gahunda y’ubushakashatsi bwa mbere.Ubushakashatsi nyamukuru bwa Jeannin bwibanze ku guteza imbere uburyo bwo kurwanya isuri ku nkombe - akora ubushakashatsi ku kuntu amabuye y’amabuye yashyinguwe mu cyuma cy’insinga hejuru y’inyanja ashobora gukora nka sima karemano, agafasha guhagarika imyanda munsi y’ingomero cyangwa ku mucanga.
Jeannin yatangije umushinga muri New Caledoniya kugirango hamenyekane niba mesh ishobora gufata umutego uhagije wibyuma bifasha kwiga amateka yanikelkwanduza kurubuga.Yaravuze ati: “Ariko igihe twabonye ko dushobora gufata nikel nyinshi, twatangiye gutekereza ku nganda zishobora gukoreshwa.”
Christine Orians, umuhanga mu by'imiti y’ibidukikije muri kaminuza y’Ubwongereza ya Columbiya i Vancouver, avuga ko ubwo buryo budashobora gukuraho nikel gusa, ahubwo ko bushobora no gukuramo ibindi byuma.Yatangarije Chemistry World ati: "Imvura igwa ntabwo ihitamo cyane."Ati: "Sinzi niba byagira akamaro mu gukuraho ibyuma bifite ubumara buhagije udakuyeho ibyuma bishobora kuba ingirakamaro nk'icyuma."
Ariko, Jeannine ntahangayikishijwe nuko sisitemu, iyo ikozwe ku rugero runini, izambura inyanja amabuye y'agaciro.Ibice 3% gusa bya calcium na 0.4% bya magnesium byavanywe mu mazi mu gihe cy’ubushakashatsi, akavuga ko ibyuma biri mu nyanja ari byinshi bihagije ku buryo bitagira ingaruka kuri byinshi.
By'umwihariko, Jeannin yavuze ko gahunda nk'iyi ishobora koherezwa ahantu hafite amazi menshi ya nikel, nk'icyambu cya Nouméa, kugira ngo agabanye amafaranga arangirira mu nyanja.Irasaba kugenzurwa gake kandi irashobora guhuzwa ningufu zishobora kongera ingufu nkizuba.Nickel nibindi byanduza byafashwe mubipimo birashobora kugarurwa no gukoreshwa.
Jeannin yavuze ko we na bagenzi be bakorana n’amasosiyete yo mu Bufaransa na New Caledoniya kugira ngo bategure umushinga w’icyitegererezo ufasha kumenya niba ubwo buryo bushobora gutangizwa mu bucuruzi.
