Sodium Cyanide: Ntchito Zofunika Kwambiri pa Migodi ndi Kupitilira

Kodi Sodium Cyanide Ndi Yowopsa Motani?

Sodium cyanide ndi ufa wa crystalline woyera kapena ma granules omwe ali ndi hygroscopic ndipo ali ndi fungo lopweteka la amondi. Amasungunuka kwambiri m'madzi ndipo amasungunuka mosavuta kupanga hydrogen cyanide, yankho lake lamadzi ndi la alkaline kwambiri. Ndi zofunika zofunika mankhwala zopangira. Makamaka, ndi poizoni kwambiri; kukhudzana ndi zilonda zapakhungu, kupuma, kapena kumeza ngakhale pang'ono kungayambitse poizoni ndi imfa.

Pogwiritsa ntchito LD50 yomwe imatchulidwa kawirikawiri (mlingo wofunika kupha theka la zinyama zoyesedwa mkati mwa nthawi yeniyeni), arsenic ili ndi LD50 ya 14.6 mg / kg (pakamwa mu makoswe), pamene Sodium cyanide ali ndi LD50 ya 6.44 mg/kg (mkamwa mu makoswe). Izi zikutanthauza kuti Sodium Cyanide ndi mphamvu pafupifupi katatu kuposa arsenic.

Chochititsa mantha kwambiri ndi chakuti izi ndizoopsa kwambiri cyanides Sungunulani mosavuta m'madzi, zomwe zimatsogolera ku zotsatira zofulumira. Imfa imatha kuchitika mkati mwa mphindi 15 mpaka ola la 1, kusiya akatswiri azachipatala ali ndi nthawi yochepa yopulumutsa. Poyerekeza, arsenic amachita pang'onopang'ono; Zizindikiro sizingawonekere mpaka ola limodzi mutadya, ndipo imfa ikhoza kuchitika maola angapo kapena tsiku lotsatira.

Kugwiritsa Ntchito Mafakitale a Sodium Cyanide

M'zaka zaposachedwapa, ntchito za sodium cyanide zafala kwambiri. Pakalipano, kumwa kwa sodium cyanide makamaka kumapangidwa ndi mankhwala, kuwerengera pafupifupi 40% ya msika; gawo lazamankhwala limakhala pafupifupi 10%; mankhwala ophera tizilombo amakhala pafupifupi 8%; ndi makampani opanga magetsi amawerengera pafupifupi 20%. Ntchito yotsalayo ndi ya mankhwala abwino. M'zaka zaposachedwa, chifukwa chakukula kwa golide, kufunikira kwa sodium cyanide mumigodi kwakula kwambiri. Mwachitsanzo, mu 2013. malonda a sodium cyanide omwe amagwiritsidwa ntchito pochotsa golide anali 2 mpaka 3 nthawi ya 2012. ndipo msika wa mankhwala ophera tizilombo wawonanso kuwonjezeka, makamaka kwa glyphosate ndi zinthu zofanana.

1. Mitundu

Sodium cyanide ingagwiritsidwe ntchito kupanga utoto. Mitundu yomwe imatha kupangidwa pano ikuphatikiza Yellow 139. Yellow 150. indigo, brilliant blue, fluorescent whitening agent VBL, ndi Disperse Green GL, pakati pa ena.

2. Mankhwala

Sodium cyanide itha kugwiritsidwa ntchito popanga mankhwala apakatikati, kupereka zida zofunikira pazogulitsa zomaliza. Mankhwala odziwika bwino ndi penicillin, pregabalin, ketoprofen, tranexamic acid, vitamini B6. kupatsidwa folic acid, guanine, acyclovir, gabapentin, butyrophenone, barbiturates, fluoroquinolones, caffeine, chifuwa suppressants, chapamimba mankhwala, analgesics, berberine, atorvastatin, ndi phenylpropanolamine.

3. Mankhwala ophera tizilombo

Sodium cyanide ingagwiritsidwe ntchito kupanga mankhwala ophera tizilombo, omwe amagwiritsidwa ntchito kwambiri ku mbewu ndi ndiwo zamasamba. Mankhwala opha tizilombo ndi glyphosate, cypermethrin, paraquat, cyantraniliprole, sulfentrazone, pyraclostrobin, benzoylpropionic acid, oxime esters, atrazine, cyanazine, ndi mankhwala osiyanasiyana oletsa matenda a mpunga.

4. Kusintha kwamagetsi

Sodium cyanide imatha kupanga ma complexes okhala ndi zitsulo zambiri, kuwapangitsa kuti azigwiritsidwa ntchito kwambiri pamakampani opanga ma electroplating ngati electrolyte yamkuwa, cadmium, zinki, ndi siliva. Ma ion complexes azitsulo mu ma electrolytewa amatha kuyika pamwamba pazida zogwirira ntchito, ndikupanga filimu yopyapyala yomwe imateteza zinthu zachitsulo.

5. Migodi

Sodium cyanide imatha kusungunula golidi ndi siliva, ndikupanga ma cyanide complexes osungunuka, ndichifukwa chake amagwiritsidwa ntchito popanga migodi pochotsa zitsulo zagolide, siliva, ndi zopanda chitsulo. M'migodi ya golide yocheperako, golide wambiri amachotsedwa pogwiritsa ntchito njira ya "mulu wa leaching" ndi sodium cyanide. Njira yochotsera iyi ili ndi phindu lalikulu la mtengo. Njira ya "mulu wa leaching" imaphatikizapo kupopera mankhwala a sodium cyanide pa mulu wa ore, kuti zinthu zomwe zakhudzidwazo zisungunuke mumtsuko, momwe golide amachotsedwa. Ngakhale Cyanides Amadziwika kuti ndi othandiza kwambiri pochotsa golide, kuwopsa kwawo kumabweretsa nkhawa, ndipo zinyalala za cyanide zimatha kuwononga kwambiri chilengedwe. Choncho, njira zosiyanasiyana, kuphatikizapo chlorination, acidification, ndi activated carbon adsorption catalytic oxidation, amagwiritsidwa ntchito ku China pochiza cyanide tailings. Njira zabwino zochotsera golide zimaphatikizapo kugwiritsa ntchito njira zopanda cyanide komanso zotsika za cyanide.

6. Ntchito Zina

Kuphatikiza pa zomwe tafotokozazi, sodium cyanide itha kugwiritsidwanso ntchito popanga amino acid, L-carnitine, lactic acid, creatine, chelating agents, cyanate esters, UV absorbers, stabilizers kuwala, ndi zonunkhira, pakati pa mankhwala ena.

Sodium cyanide, kodi anthu angadziteteze bwanji?

Chofunika kwambiri ndi:Anthu omwe ali panja akuyenera kusamuka kupita kudera lomwe lili pamtunda wa makilomita awiri kuchokera pamalo pomwe pachitika ngozi ndi kukakwera mphepo kuti asakhumane ndi mankhwala aliwonse.

Khungu kukhudzana:Chotsani nthawi yomweyo zovala zomwe zawonongeka ndikutsuka bwino malo omwe akhudzidwawo ndi madzi oyenda kapena 5% sodium thiosulfate solution kwa mphindi zosachepera 20. Pitani kuchipatala msanga.

Kuyanjana kwa diso:Nthawi yomweyo muzimutsuka m'maso ndi madzi othamanga ambiri kapena saline solution kwa mphindi 15. Pitani kuchipatala msanga.

Inhalation: Chokani pamalopo mwachangu kupita kumalo komwe kuli mpweya wabwino. Ngati kupuma kumachitika, perekani mpweya. Ngati kupuma ndi kugunda kwa mtima zasiya, nthawi yomweyo gwirani kupuma mochita kupanga (musagwiritse ntchito pakamwa ndi pakamwa) ndi kukakamiza pachifuwa.

Kusakaniza: Imwani madzi ofunda okwanira kuti musanze. Gwiritsani ntchito 1:5000 potassium permanganate solution kapena 5% sodium thiosulfate solution potsuka m'mimba. Pitani kuchipatala msanga.

Kuti mudziwe zambiri zamaluso? Lumikizanani nafe!

Malangizo Ofunda: Ngati mukufuna kudziwa zambiri, monga mawu, zinthu, mayankho, ndi zina.
