Kungani i-Sodium Cyanide ibukwa Kakhulu?

I-sodium cyanide ( NaCN ) ibilokhu iyindaba ebaluleke kakhulu futhi ekhathazayo emikhakheni eyahlukahlukene. Lokhu kungenxa yemvelo yayo enobuthi obukhulu kanye nokusetshenziswa kwayo okubanzi embonini.

ubuthi: Usongo Olubulalayo

I-sodium cyanide ngokweqile anobuthi kuya ku-huMAns. Ngisho nenani elincane, elingama-5% kuphela ITIYEisipuni, kungaba ebulalayoUma ingena emzimbeni womuntu, iyahlukana ibe i-cyanide ions (CN⁻). Lawa ma-ion anobuhlobo obuqinile ne- iron ku-cytochrome oxidase, i-enzyme ebalulekile kuma-electron Ezokuthutha uchungechunge ekuphefumuleni kwamaseli. Ngokubopha ku- iron, I-Cyanide ions kuvimbela umsebenzi we-enzyme, kuvimbela ukudluliselwa kwama-electron futhi ekugcineni kuphazamisekeUPting ikhono lomzimba lokukhiqiza amandla ngesimo se-ATP. Lokhu kuholeleukungasebenzi kahle kwamaseli ngokushesha, I-Lactic Acidi-osis (njengoba amangqamuzana eshintshela ku-metabolism engena-aerobic), futhi ekugcineni afe. ​​Izimpawu ze- i-sodium cyanideubuthi Faka isiphefumulaukucindezeleka, ukudlikizela, ukulahlekelwa ukwazi, kanye nokuma kwenhliziyo. Ngenxa yalokhu kubulala okukhulu, noma yikuphi okungenzeka ukuchayeka kuya I-Sodium Cyanide,whether ezingozini zezimboni noma kwezinye izimo, ngokushesha kuphakamisa umphakathi obalulekile Impilo Nokuphepha ukukhathazeka.

Kugcwele izicelo zezimboni

Izimayini zegolide

Enye yokuqala Usetshenziswa of I-sodium cyanide ikhona izimayini zegolide imboni. Iningi lezimboni zomhlaba igolide ayitholakali ezinhlayiyeni ezinkulu kodwa itholakala njengezinhlayiya ezincane ezisakazeke emadwaleni. Ukukhipha igolide kulezi zinsimbi, inqubo ebizwa ngokuthi I-Cyanidation ivame ukusetshenziswa. Ngemva kokuba i-ore isimbiwe futhi yagaywa yaba yimpuphu ecolekile, ifakwa esixazululweni se- I-Sodium CyanideIgolide lakha izibopho eziqinile ne- i-cyanide ama-molecule, i-creating encibilikayoigolide - cyanide complexLezi zinkimbinkimbi zingahlukaniswa kwezinye izingxenye amaminerali ensimbini, njengoba kunjalo inyibilika emanziniNgemva kwalokho, zinc yengezwa esixazululweni, esisabela negolide - I-Cyanide ama-complex, okwenza igolide liqaleI-CIPiphuma njengeqinile. Lo mkhiqizo wokugcina ube usuncibilikiswa ukuze kuhlukaniswe igolide elihlanzekile. Isidingo somhlaba wonke segolide, esiqhutshwa yizici ezifana nokwenza ubucwebe, ukutshalwa kwezimali, kanye izicelo zezimboni, kusho ukuthi inani elikhulu I-sodium cyanide isetshenziswa ngegolide Imisebenzi yezimayini emhlabeni wonke. Ngenxa yalokho, noma yiziphi izinkinga ezihlobene i-sodium cyanide kulo mongo, njengokuthi Ephephileukuphatha, isitoreji, Futhi Transportation, zidonsela ukunaka okukhulu ngenxa yokubaluleka kwezomnotho kwale mboni.

Izincwajana zemininingwane Ukusetshenziswa Kwezimboni

sodium i-cyanide idlala indima ebalulekile nakwezinye izimboni. Emkhakheni we- i-electroplating, isetshenziswa njengengxenye kwezinye izinto Ukugeza okugezas. Kuyasiza ku I-ACHukuvikela ungqimba olubushelelezi nolufanayo lwezinsimbi ezifana Copper, silver, i-cadmium, kanye Zinc ezindaweni ezahlukene. Ku- Ukukhiqiza of Amakhemikhali e-organics, sodium i-cyanide isebenza njengento ebalulekile yokuqala. Isibonelo, ku- Synthesis kweqiniso izidakamizwa, isetshenziselwa ukwethula iqembu le-cyano (-CN) kuma-molecule e-organic, okubalulekile ekwakhekeni kwamakhemikhali amaningi abalulekile emithi. Iphinde isetshenziswe ku- production of imicu yokwenziwa, amapulasitiki, Futhi amadayi. Ku Imboni yokudaya, ihilelekile ekwakhiweni kwamakhemikhali afana (I-Cyanuric chloride), okuyinto ebalulekile maphakathi ukwenza Amadayi Asebenzayo futhi isebenza njenge- impahla eluhlaza ukukhiqiza izibani zokukhanyisa ezibonakalayo. Njengoba zibalulekile kulezi zinhlobo ezahlukene ze-optical brighteners. izinqubo zezimboninoma yikuphi ukuphazamiseka ekuhlinzekweni, ekuphathweni, noma ukuphepha of Sodium i-cyanide ingaba nemiphumela efinyelela kude kwezomnotho.

Izehlakalo kanye Nezimo ZazoI-PACt

Izehlakalo ezidumile ezihilela i-sodium cyanide ziye zaba negalelo elikhulu ekuveleni kwayo emehlweni omphakathi. Isibonelo, ukuqhuma kweTianjin ngo-2015 kwakuyisenzakalo esibuhlungu esaletha i-sodium cyanide ekukhanyeni. Endaweni yokuqhuma, kwatholakala inqwaba yamathani angu-700 e-sodium cyanide, okwakungaphezu kokuphindwe izikhathi ezingu-70 kunomkhawulo osemthethweni. Ukuqhuma kwaphakamisa ukukhathazeka mayelana nokukhululwa okungenzeka kwale Chemical enobuthi obukhulu emvelweni . Ukube i-sodium cyanide yayikhishwe futhi yahlangana namanzi noma amazinga okushisa aphezulu, ngabe yakha igesi ye-hydrogen cyanide , into eyingozi kakhulu futhi eguquguqukayo. I-hydrogen cyanide inobuthi kakhulu uma ihogelwa futhi ingasakazeka ngokushesha emoyeni, ibeke impilo yabantu abaseduze engozini. Nakuba iziphathimandla zaseShayina zathatha isinyathelo esisheshayo sokuphatha lesi simo, njengokwelapha ukuchitheka nge -hydrogen peroxide ukunciphisa ukwakheka kwamakhemikhali ayingozi kakhulu, lesi sigameko sisagqamise izingozi ezibalulekile ezihambisana nokugcinwa nokuphathwa kwe-sodium cyanide. Ukuqwashisa komphakathi ngezingozi ezingaba khona ze -sodium cyanide kwanda kakhulu, futhi kwaholela ekuhlolweni okukhulu kwemithethonqubo yokuphepha kanye nemikhuba ezimbonini ezibhekana naleli khemikhali.

Ekuphetheni, ubuthi obuphezulu be-sodium cyanide , ukusetshenziswa kakhulu ezimbonini ezibalulekile njengezimayini zegolide kanye nokukhiqizwa kwamakhemikhali , kanye nokubandakanyeka kwayo ezigamekweni ezinkulu konke kunegalelo esimweni sayo njengekhemikhali eqashelwa eduze. Isidingo sokulinganisela ukusetshenziswa kwayo kwezimboni nezinyathelo zokuphepha eziqinile zokuvikela impilo yabantu kanye nendawo ezungezile insimbi kuseyinselele enkulu.
