Sodium Cyanide: Mabuɗin Amfani da Ma'adinai da Bayan Gaba

Yaya Sodium Cyanide yake da guba?

sodium cyanide wani farin crystalline foda ne ko granules wanda yake hygroscopic kuma yana da kamshin almond mai ɗaci. Yana da narkewa sosai a cikin ruwa kuma yana iya yin hydrolyzes don samar da hydrogen cyanide, tare da maganin ruwan sa yana da ƙarfi alkaline. Abu ne mai mahimmanci na asali na asali. Musamman ma, yana da guba sosai; cudanya da raunukan fata, shakar numfashi, ko sha ko da kadan na iya haifar da guba da mutuwa.

Yin amfani da LD50 da aka saba magana (kashin da ake buƙata don kashe rabin gwajin dabbobi a cikin ƙayyadadden lokaci), arsenic yana da LD50 na 14.6 mg/kg (na baka a beraye), yayin da Sodium cyanide yana da LD50 na 6.44 mg/kg (na baka a berayen). Wannan yana nufin haka sodium Cyanide yana da ƙarfi kusan sau uku fiye da arsenic.

Abin da ya fi ban tsoro shi ne gaskiyar cewa waɗannan masu guba sosai cyanides narke cikin sauƙi a cikin ruwa, yana haifar da sakamako mai sauri. Mutuwa na iya faruwa a cikin mintuna 15 zuwa sa'a 1, yana barin ƙwararrun likitoci da ƙayyadaddun lokaci don ceto. A kwatanta, arsenic yana aiki da hankali; Alamun ba za su bayyana ba har sai sa'a guda bayan an sha, kuma mutuwa na iya faruwa da yawa sa'o'i ko ma kwana ɗaya bayan haka.

Amfanin Masana'antu na Sodium Cyanide

A cikin 'yan shekarun nan, da aikace-aikace na sodium cyanide sun ƙara yaɗuwa. A halin yanzu, amfani da sodium cyanide shine da farko don haɗin sinadarai, wanda ya kai kusan 40% na kasuwar kasuwa; bangaren harhada magunguna ya kai kusan kashi 10%; magungunan kashe qwari sun kai kusan 8%; da kuma masana'antar sarrafa lantarki lissafin kusan kashi 20%. Sauran amfanin yana cikin sinadarai masu kyau. A cikin 'yan shekarun nan, tare da karuwar bukatar zinariya, buƙatar sodium cyanide a cikin ma'adinai ya karu sosai. Misali, a cikin 2013. Siyar da siyar da sodium cyanide da aka yi amfani da ita don hakar zinare ya ninka sau 2 zuwa 3 na 2012. kuma kasuwar magungunan kashe qwari ta kuma ga karuwa, musamman ga glyphosate da makamantansu.

1. Rini

Sodium cyanide za a iya amfani da su hada rini. Rinyoyin da za a iya haɗa su a halin yanzu sun haɗa da Yellow 139. Yellow 150. indigo, blue blue, fluorescent whitening agent VBL, da Dissperse Green GL, da sauransu.

2. Magungunan Magunguna

Sodium cyanide za a iya amfani da su hada magunguna masu tsaka-tsakin, samar da muhimman albarkatun kasa na ƙarshe na magunguna. Magunguna na yau da kullun sun haɗa da penicillin, pregabalin, ketoprofen, tranexamic acid, bitamin B6. folic acid, guanine, acyclovir, gabapentin, butyrophenone, barbiturates, fluoroquinolones, caffeine, suppressants, magungunan ciki, analgesics, berberine, atorvastatin, dan phenylpropanolamine.

3. Maganin kashe qwari

Ana iya amfani da sodium cyanide don haɗa magungunan kashe qwari, waɗanda ake amfani da su sosai ga amfanin gona da kayan lambu. Magungunan kashe qwari na yau da kullun sun haɗa da glyphosate, cypermethrin, paraquat, cyantraniliprole, sulfentrazone, pyraclostrobin, benzoylpropionic acid, oxime esters, atrazine, cyanazine, da ma'aikatan sarrafa cututtukan shinkafa daban-daban.

4. Yin lantarki

Sodium cyanide na iya samar da hadaddun abubuwa masu karafa da yawa, wanda ya sa ake amfani da shi a masana'antar lantarki a matsayin electrolyte don jan karfe, cadmium, zinc, da azurfa. Ƙarfe ion hadaddun a cikin wadannan electrolytes iya ajiya a saman workpieces, forming wani bakin ciki fim cewa kare karfe kayayyakin.

5. Karafa

Sodium cyanide yana da ikon narkar da zinare da azurfa, yana samar da rukunin cyanide masu narkewa, wanda shine dalilin da ya sa ake amfani da shi wajen hakar gwal, azurfa, da karafa marasa ƙarfe. A cikin ma'adinan zinare marasa daraja na gida, ana yin hakar zinare da yawa ta hanyar amfani da hanyar "heap leaching" tare da sodium cyanide. Wannan tsarin hakar yana da fa'idar tsada mai mahimmanci. Hanyar “heap leaching” ta ƙunshi fesa maganin sodium cyanide a kan tulin tama, da barin abubuwan da aka yi niyya su narke cikin maganin, daga nan ne ake samun zinari. Ko da yake Cyanides ana gane su azaman ingantattun kayan leaching na zinari, yanayinsu mai guba yana haifar da damuwa, kuma sharar cyanide na iya lalata muhalli sosai. Saboda haka, hanyoyi daban-daban, ciki har da chlorination, acidification, da kunna carbon adsorption catalytic oxidation, ana amfani da su a kasar Sin don maganin wutsiyar cyanide. Mafi kyawun ayyuka don hakar gwal sun haɗa da amfani da zabin cyanide maras kyau da ƙananan cyanide.

6. Sauran Amfani

Baya ga aikace-aikacen da ke sama, ana iya amfani da sodium cyanide don shirya amino acid, L-carnitine, lactic acid, creatine, chelating agents, cyanate esters, UV absorbers, stabilizers light, da turare, a tsakanin sauran kayayyakin sinadarai.

Sodium cyanide, ta yaya mutane za su iya kare kansu?

Abu mafi mahimmanci shine:mutanen da ke waje su tashi zuwa wani yanki aƙalla kilomita 2 daga wurin da hatsarin ya faru kuma su tashi sama don guje wa haɗuwa da kowane sinadari.

Saduwa ta fata:Nan da nan cire gurbatattun tufafi kuma a wanke yankin da abin ya shafa da ruwan gudu ko maganin 5% sodium thiosulfate na akalla mintuna 20. Nemi kulawar lafiya da sauri.

Ido lamba:Nan da nan kurkure idanu tare da yawan ruwan gudu ko ruwan gishiri na akalla mintuna 15. Nemi kulawar lafiya da sauri.

Inhalation: Da sauri barin wurin zuwa wani yanki mai tsabta. Idan wahalar numfashi ta faru, samar da iskar oxygen. Idan numfashi da bugun zuciya sun daina, nan da nan yi numfashin wucin gadi (kada a yi amfani da baki-da-baki) da damtse kirji.

Ingestion: A sha isasshen ruwan dumi don haifar da amai. Yi amfani da maganin 1:5000 potassium permanganate ko maganin 5% sodium thiosulfate don wankewar ciki. Nemi kulawar lafiya da sauri.
