Iwe unoziva nezve kushandiswa kwe sodium cyanide?

Sodium cyanide, ine kemikari formula NaCN, ikomboni yakawana kutariswa kwakanyanya nekuda kwehupfu hwayo. Nekudaro, inoitawo basa rakakosha mumaindasitiri akasiyana. Ichi chinyorwa chinotarisa mukushandiswa kwakasiyana-siyana kwe Sodium cyanide muzvikamu zvakasiyana.

1. Mining Indasitiri

Kuchera Goridhe neSirivha

Imwe yevanonyanya kuzivikanwa Applications of Sodium Cyanide iri mukutorwa kwegoridhe nesirivha kubva mumatombo avo. Iyi nzira, inozivikanwa se cyanidation, inovimba nekugona kweiyo cyanide ions kuumba yakagadzikana macomplexes ane goridhe nesirivha. Pamberi peokisijeni nemvura, simbi yegoridhe inopinda oxidation uye inonyunguduka mumushonga we cyanide, zvichiita kuti pave nekugadzirwa kwegoridhe - cyanide complex. Iyi nzira inoshanda zvakanyanya uye yanga iri chiyero chekucherwa kwegoridhe nesirivha kwemakore akawanda. Inogonesa kudzoreredzwa kwesimbi dzakakosha kubva kune yakaderera-giredhi ores, iyo inogona kunge isingaite zvehupfumi kugadzirisa uchishandisa dzimwe nzira. Semuenzaniso, mumigodhi mikuru yegoridhe pasi rose, sodium cyanide inoshandiswa muhuwandu hwakawanda kuchera goridhe. Mune mimwe migodhi yeAfrica neSouth America, zviuru zvematani e<em>ore zvinorapwa nemishonga ye<em>cyanide zuva nezuva kuti vawane goridhe shoma.

Imwe Metal Processing

Sodium cyanide inoshandiswawo mukupatsanura uye kucheneswa kwemamwe masimbi akadai semhangura, zingi, uye nickel. Munguva yemaitiro aya, cyanide inogona kusarudza kusunga nemamwe simbi, ichibvumira kupatsanurwa kwavo kubva kune tsvina kana mamwe simbi mune ore. Somuenzaniso, mumhangura - Indasitiri yezvicherwa, cyanide inogona kushandiswa kupatsanura mhangura kubva kune dzimwe simbi dzakabatanidzwa mune ore body. Izvi zvinowanikwa nekugadzirisa pH uye kusungirirwa kweiyo cyanide mhinduro kunanga chaiyo simbi - cyanide yakaoma maumbirwo.

2. Electroplating

Mu electroplating indasitiri, sodium cyanide chinhu chakakosha mukugezesa bhati. Inofambisa kuiswa kwesimbi semhangura, sirivha, cadmium, uye zinc pane akasiyana substrates. Cyanide ions mune yeplating solution inoshanda seanoomesera vamiririri. Vanoumba ma complexes ane simbi ions, iyo inobatsira mukudzora chiyero chesimbi deposition. Nekuda kweizvozvo, yakawedzera yunifomu uye yakanamatira simbi yesimbi inowanikwa pamusoro pechinhu chiri kuputirwa. Semuenzaniso, mukugadzirwa kwezvishongo zvepamusoro-soro, electroplating nesirivha kana ndarama inowanzobatanidza kushandiswa kwecyanide - based plating solutions. Kuvepo kwesodium cyanide kunovimbisa kuti simbi yakakosha inoiswa zvakaenzana, ichipa zvishongo kupera uye kupenya. Muindasitiri yemotokari, zvikamu zvakaita semabumpers uye zvishongedzo zvekushongedza zvinowanzoiswa magetsi uchishandisa cyanide - ine zvigadziriso zvekuvandudza chitarisiko chavo uye kusagadzikana kwekuora.

3. Chemical Synthesis

Kugadzirwa kweOrganic Compounds

Sodium cyanide chinhu chakakosha reagent mune organic synthesis. Inogona kushandiswa kusuma boka recyano (-CN) muma organic molecules. Iri inhanho yakakosha mukuumbwa kweakawanda organic makomisheni, anosanganisira nitriles, ayo anochinja-chinja mabhuroko ekuvaka muorganic chemistry. Semuenzaniso, mukugadzirwa kweacrylonitrile, iyo inoshandiswa kugadzira mafiber ekugadzira senge acrylic uye modacrylic, sodium cyanide inogona kushandiswa mune imwe yematanho ekuita. Kuita pakati peyakakodzera organic halide uye sodium cyanide kunotungamirira pakuumbwa kwe nitrile kuburikidza ne nucleophilic substitution reaction.

Synthesis of Pharmaceuticals uye Agrochemicals

Muindasitiri yemishonga, sodium cyanide inoshandiswa mukugadzirwa kwemishonga yakati wandei. Semuenzaniso, inobatanidzwa mukugadzirwa kwemamwe mishonga inorwisa mabhakitiriya, mavhitamini, uye mishonga inorwisa kuzvimba. Mukubatanidzwa kwevhitamini B12. cyanide inoshandiswa mukugadzirira kweakakosha epakati makomisheni. Mundima yeagrochemical, sodium cyanide inoshandiswa mukugadzira mishonga yezvipembenene nemishonga yesora. Mimwe mishonga inouraya zvipembenene nefungicides ine zvimiro zvinobva mukuita kunosanganisira sodium cyanide. Mishonga iyi inobatsira mukudzivirira zvirimwa kubva kutumbuyu nezvirwere, nokudaro zvichiwedzera goho rekurima.

4. Zvimwe Zvikumbiro

Rodent Control

Nekuda kwekunyanyisa kwayo, sodium cyanide yakashandiswa serodenticide. Inogona kushandiswa kudzora huwandu hwemakonzo, mbeva, uye mamwe makonzo. Nekudaro, kushandiswa kwayo muchirevo chechinyorwa ichi kunodzorwa zvakanyanya nekuda kwenjodzi dzazvinokonzeresa kune dzisiri-chinangwa mhando uye zvakatipoteredza. Mune dzimwe nzvimbo uko kubatwa nemakonzo kwakakomba uye dzimwe nzira dzekudzora dzakaratidza kusashanda, sodium cyanide - based baits inogona kushandiswa pasi pekutariswa kwakasimba. Makonzo anodya chirauro, uye cyanide inokurumidza kuita pahurongwa hwavo hwetsinga, zvichitungamira kurufu.

Kucheneswa Kwesimbi uye Kupukuta

Sodium cyanide inogona kushandiswa mukuchenesa simbi uye kukwenenzvera mabasa. Inobatsira mukubvisa maokisi uye zvimwe zvinosvibisa pamusoro pesimbi. Panyaya yemamwe masimbi, iyo cyanide inogona kuita nekusachena kwepamusoro, ichigadzira soluble complexes inogona kushambidzwa nyore nyore. Iyi nzira inonyanya kukosha pakugadzira nzvimbo dzesimbi kuti dziwedzere kugadziriswa, sekupenda kana kusungirirwa. Semuenzaniso, muindasitiri yemuchadenga, zvimwe simbi isati yapendwa kana kubatanidzwa pamwe chete, inogona kurapwa nemhinduro dzine sodium cyanide kuti ive nechokwadi chenzvimbo yakachena uye yakatsetseka.

Mukupedzisa, sodium cyanide, kunyangwe ine chepfu, ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana. Kubva pakutorwa kwesimbi dzakakosha mumigodhi kusvika pakugadzirwa kwemishonga yakakosha, kushandiswa kwayo kwakasiyana uye kwakakosha. Nekudaro, nekuda kwehunhu hwayo hwengozi, kuchengetedzeka kwakasimba uye mirau yezvakatipoteredza iripo kuti ive nechokwadi chekubata kwayo, kuchengetedza, uye kuraswa.
