Sodium Cyanide: Tšebeliso ea Bohlokoa Merafong le Ka Ntle

Sodium Cyanide e chefo hakae?

Sodium cyanide ke phofo e tšoeu ea crystalline kapa granules e hygroscopic 'me e na le monko o monate oa almonde. E qhibiliha haholo metsing 'me e bonolo ho hydrolyzes ho etsa hydrogen cyanide, 'me tharollo ea eona ea metsi e le alkaline e matla. Ke lisebelisoa tsa bohlokoa tsa motheo tsa lik'hemik'hale. Ka ho hlakileng, e chefo e feteletseng; ho kopana le maqeba a letlalo, ho hema, kapa ho ja esita le hanyenyane ho ka lebisa ho chefo le lefu.

Ho sebelisa LD50 e atisang ho boleloa (tekanyo e hlokahalang ho bolaea halofo ea liphoofolo tsa teko ka nako e behiloeng), arsenic e na le LD50 ea 14.6 mg / kg (molomo ka likhoto), ha Sodium cyanide e na le LD50 ea 6.44 mg / kg (molomo ho likhoto). Sena sebolela seo Sodium cyanide e matla ho feta arsenic ka makhetlo a mararo.

Ho tšosang le ho feta ke taba ea hore tsena li chefo haholo li-cyanides qhala habonolo ka metsing, e lebisang liphellong tse potlakileng. Lefu le ka etsahala nakong ea metsotso ea 15 ho isa ho hora ea 1, e siea litsebi tsa bongaka li na le nako e fokolang haholo ea ho pholosa. Ha ho bapisoa, arsenic e sebetsa butle butle; matšoao a ka 'na a se ke a bonahala ho fihlela hora ka mor'a ho ja,' me lefu le ka hlaha lihora tse 'maloa kapa esita le letsatsi hamorao.

Tšebeliso ea indasteri ea sodium cyanide

Lilemong tsa morao tjena, likopo tsa sodium cyanide li se li atile ka ho eketsehileng. Hona joale, tšebeliso ea sodium cyanide ke haholo-holo bakeng sa metsoako ea lik'hemik'hale, e leng karolo ea 40% ea karolo ea 'maraka; lefapha la meriana le nka karolo ea 10 lekholong; chefo e bolaeang likokoanyana e etsa hoo e ka bang 8%; le ea indasteri ea motlakase e etsa hoo e ka bang 20%. Tšebeliso e setseng ke lik'hemik'hale tse ntle. Lilemong tsa morao tjena, ka tlhokahalo e ntseng e eketseha ea khauta, tlhokahalo ea sodium cyanide merafong e eketsehile haholo. Mohlala, ka 2013. thekiso ea sodium cyanide e sebelisoang bakeng sa ho ntšoa ha khauta e ne e le makhetlo a 2 ho isa ho a 3 ho feta a 2012. mme mmaraka oa chefo e bolaeang likokoanyana le ona o bone ho eketseha, haholo-holo bakeng sa glyphosate le lihlahisoa tse tšoanang.

1. Lidae

Sodium cyanide e ka sebelisoa ho etsa lidae. Lidae tse ka etsoang hajoale li kenyelletsa Yellow 139. Yellow 150. indigo, brilliant blue, fluorescent whitening agent VBL, le Disperse Green GL, har'a tse ling.

2. Meriana

Sodium cyanide e ka sebelisoa ho kopanya li-intermediate tsa meriana, ho fana ka lisebelisoa tsa bohlokoa bakeng sa lihlahisoa tsa ho qetela tsa meriana. Lithethefatsi tse tloaelehileng li kenyelletsa penicillin, pregabalin, ketoprofen, tranexamic acid, vithamine B6. folic acid, guanine, acyclovir, gabapentin, butyrophenone, barbiturates, fluoroquinolones, caffeine, lithethefatsi tse thibelang sefuba, meriana ea gastric, analgesics, berberine, atorvastatin, le phenylpropanolamine.

3. Meriana e bolaeang likokoanyana

Sodium cyanide e ka sebelisoa ho kopanya chefo e bolaeang likokoanyana, e sebelisoang haholo lijalong le merohong. Likokoana-hloko tse tloaelehileng li kenyelletsa glyphosate, cypermethrin, paraquat, cyantraniliprole, sulfentrazone, pyraclostrobin, benzoylpropionic acid, oxime esters, atrazine, cyanazine, le mefuta e sa tšoaneng ea ho laola maloetse a raese.

4. Ho khetha motlakase

Sodium cyanide e ka etsa li-complexes tse nang le litšepe tse ngata, tse etsang hore e sebelisoe hangata indastering ea electroplating e le electrolyte bakeng sa koporo, cadmium, zinki le silevera. Lisebelisoa tsa ion tsa tšepe li-electrolyte tsena li ka beha holim'a li-workpieces, tsa etsa filimi e tšesaane e sireletsang lihlahisoa tsa tšepe.

5. Merafo

Sodium cyanide e na le bokhoni ba ho qhaqha khauta le silevera, ho etsa li-complexes tsa cyanide tse qhibilihang, ke ka lebaka leo e sebelisoang merafong bakeng sa ho ntšoa ha khauta, silevera le tšepe e se nang ferrous. Meepong ea khauta ea maemo a tlase, ho ntšoa khauta e ngata ho sebelisoa mokhoa oa "heap leaching" ka sodium cyanide. Mokhoa ona oa ho hula o na le molemo o moholo oa litšenyehelo. Mokhoa oa "heap leaching" o kenyelletsa ho fafatsa motsoako oa sodium cyanide holim'a qubu ea ore, ho lumella likarolo tse shebiloeng hore li qhibilihe ka har'a tharollo, eo khauta e tsoang ho eona. Leha ho le joalo Li-cyanides li hlokomeloa e le lisebelisoa tse sebetsang hantle tsa ho tsoa ha khauta, tlhaho ea tsona e chefo haholo e hlahisa matšoenyeho, 'me litšila tsa cyanide li ka senya tikoloho haholo. Ka hona, mekhoa e fapaneng, ho kenyelletsa chlorination, acidification, le activated carbon adsorption catalytic oxidation, e sebelisoa Chaena bakeng sa kalafo ea mehatla ea cyanide. Mekhoa e metle ea ho ntšoa ha khauta e kenyelletsa ho sebelisa mefuta e meng e se nang cyanide le e tlase ea cyanide.

6. Lisebelisoa tse ling

Ntle le lits'ebetso tse kaholimo, sodium cyanide e ka boela ea sebelisoa ho lokisa li-amino acid, L-carnitine, lactic acid, creatine, chelating agents, cyanate esters, li-absorber tsa UV, li-stabilizer tse khanyang le monko o monate, har'a lihlahisoa tse ling tsa lik'hemik'hale.

Sodium cyanide, batho ba ka itšireletsa joang?

Ntho ea bohlokoa ka ho fetisisa ke:batho ba ka ntle ba lokela ho fallela sebakeng se bohōle ba lik'hilomithara tse 2 ho tloha sebakeng sa kotsi 'me ba tsohe moea ho qoba ho kopana le lik'hemik'hale life kapa life.

Ho ikopanya le letlalo:Hang-hang tlosa liaparo tse silafetseng 'me u hlatsoe sebaka se amehileng ka ho feletseng ka metsi a phallang kapa tharollo ea sodium thiosulfate ea 5% bonyane metsotso e 20. Batla thuso ea bongaka hang-hang.

Ho kopana le mahlo:Hang-hang hlatsoa mahlo ka metsi a mangata a phallang kapa tharollo ea saline bonyane metsotso e 15. Batla thuso ea bongaka hang-hang.

Inhalation: Tloha sebakeng seo kapele ho ea sebakeng se nang le moea o hloekileng. Haeba mathata a ho hema a hlaha, fana ka oksijene. Haeba ho hema le ho otla ha pelo ho emisa, hang-hang etsa phefumoloho ea maiketsetso (u se ke ua sebelisa molomo ho ea molomong) le ho hatella sefuba.

Ho kenella: Noa metsi a futhumetseng a lekaneng ho etsa hore motho a hlatse. Sebelisa motsoako oa 1:5000 oa potassium permanganate kapa 5% sodium thiosulfate tharollo bakeng sa ho hlatsoa mala. Batla thuso ea bongaka hang-hang.
