Sodium Cyanide: Tšebeliso ea Bohlokoa Merafong le Ka Ntle

Sodium Cyanide e chefo hakae?

Sodium cyanide ke phofo e tšoeu e kristale kapa li-granule tse nang le monko o bobebe oa almonde. E qhibiliha haholo metsing 'me e fetoha hamonate habonolo ho etsa hydrogen cyanide, 'me tharollo ea eona ea metsi e le alkaline e matla. Ke thepa ea bohlokoa ea lik'hemik'hale tse tala. Haholo-holo, e chefo haholo; ho kopana le maqeba a letlalo, ho hema, kapa ho monya esita le karolo e nyane ho ka lebisa chefong le lefung.

Ha ho sebelisoa LD50 e atisang ho boleloa (tekanyo e hlokahalang ho bolaea halofo ea liphoofolo tse lekiloeng ka nako e behiloeng), arsenic e na le LD50 ea 14.6 mg/kg (e nooang ho likhoto), ha Sodium cyanide e na le LD50 ea 6.44 mg/kg (e nooang ho likhoto). Sena se bolela hore Sodium Cyanide e matla ho feta arsenic ka makhetlo a mararo.

Se tšosang le ho feta ke taba ea hore li-cyanide tsena tse chefo haholo lia qhibiliha habonolo ka metsing, e leng se lebisang liphellong tse potlakileng. Lefu le ka hlaha metsotsong e 15 ho isa ho hora e le 'ngoe, e leng se sieang litsebi tsa bongaka nako e lekanyelitsoeng haholo ea ho pholosa. Ha ho bapisoa, arsenic e sebetsa butle haholo; matšoao a ka 'na a se ke a hlaha ho fihlela hora kamora ho e ja, 'me lefu le ka hlaha lihora tse 'maloa kapa esita le letsatsi hamorao.

Tšebeliso ea indasteri ea sodium cyanide

Lilemong tsa morao tjena, ts'ebeliso ea sodium cyanide e se e atile haholo. Hona joale, ts'ebeliso ea sodium cyanide e reretsoe haholo-holo tlhahiso ea lik'hemik'hale, e leng karolo ea hoo e ka bang 40% ea karolo ea 'maraka; lefapha la meriana le etsa hoo e ka bang 10%; chefo e bolaeang likokoanyana e etsa hoo e ka bang 8%; 'me indasteri ea electroplating e etsa hoo e ka bang 20%. Ts'ebeliso e setseng e lik'hemik'haleng tse ntle. Lilemong tsa morao tjena, ka tlhoko e ntseng e hola ea khauta, tlhoko ea sodium cyanide merafong e eketsehile haholo. Mohlala, ka 2013, thekiso ea sodium cyanide e sebelisitsoeng bakeng sa ho ntša khauta e ne e le makhetlo a 2 ho isa ho a 3 ho feta a 2012. 'Me' maraka oa chefo e bolaeang likokoanyana le oona o bone keketseho, 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 bokgoni ba ho qhala kgauta le silefera, e etsa metsoako ya cyanide e qhibilihang, ke ka lebaka leo e sebediswang merafong bakeng sa ho ntsha kgauta, silefera le dimethara tse seng tsa ferrous. Merafong ya kgauta ya lapeng ya maemo a tlase, ho ntshwa ha kgauta ho ngata ho etswa ho sebediswa mokgwa wa "ho ntsha heap" ka sodium cyanide. Mokgwa ona wa ho ntsha o na le monyetla o moholo wa ditjeo. Mokgwa wa "ho ntsha heap" o kenyelletsa ho fafatsa tharollo ya sodium cyanide hodima qubu ya ore, ho dumella dikarolo tse rerilweng ho qhalana ka hara tharollo, eo kgauta e fumanwang ho yona. Le hoja Cyanide e tsejwa e le di-agent tse sebetsang tsa ho ntsha kgauta, tlhaho ya tsona e chefo haholo e baka matshwenyeho, mme ditshila tsa cyanide di ka senya tikoloho haholo. Ka hona, mekgwa e fapaneng, ho kenyeletswa le chlorination, acidification, le activated carbon adsorption catalytic oxidation, e sebediswa Chaena bakeng sa kalafo ya mesaletsa ya cyanide. Mekhoa e metle ya ho ntshwa ha kgauta e kenyeletsa ho sebedisa mekgwa e meng e se nang cyanide le e se nang 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 hore: batho ba kantle ba lokela ho balehela sebakeng se bohōle ba lik'hilomithara tse 2 ho tloha sebakeng seo kotsi e etsahetseng ho sona 'me ba tsoe moeeng ho qoba ho kopana le lik'hemik'hale leha e le life.

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

Ho sheba mahlo: Hlatsoa mahlo hang-hang ka metsi a mangata a phallang kapa tharollo ea letsoai bonyane metsotso e 15. Batla thuso ea bongaka hang-hang.

Ho hema: Tlohela sebakeng seo kapele sebakeng se nang le moya o hlwekileng. Haeba ho hlaha mathata a ho hema, fana ka oksijene. Haeba ho hema le ho otla ha pelo ho emisa, hang-hang etsa phefumoloho ya maiketsetso (o se ke wa sebedisa molomo le molomo) le ho hatella sefuba.

Ho Monya: Noa metsi a futhumetseng a lekaneng ho baka ho hlatsa. Sebelisa tharollo ea 1:5000 potassium permanganate kapa tharollo ea 5% ea sodium thiosulfate bakeng sa ho hlatsoa mpa. Batla thuso ea bongaka hang-hang.

Bakeng sa litlhahiso tse ling tsa litsebi? Iteanye le rona!

Malebela a Mofuthu: Haeba u batla ho tseba haholoanyane, joalo ka mantsoe a qotsitsoeng, lihlahisoa, tharollo, joalo-joalo.
