Iwe unoziva nezve kushandiswa kwe sodium cyanide?

Sodium cyanide , ine fomura yemakemikari NaCN, chinhu chakakurumbira zvikuru nekuda kwechepfu yayo yakawanda. Zvisinei, inoitawo mabasa akakosha mumaindasitiri akasiyana-siyana. Chinyorwa chino chinotsanangura mashandisirwo akasiyana-siyana eSodium cyanide muzvikamu zvakasiyana.

1. Mining Indasitiri

Kuchera Goridhe neSirivha

Imwe yenzira dzinozivikanwa dzekushandisa Sodium Cyanide ndeyekubvisa goridhe nesirivha kubva mumatombo avo. Maitiro aya, anozivikanwa secyanidation, anoenderana nekugona kwemaion ecyanide kugadzira complex dzakagadzikana negoridhe nesirivha. Kana paine okisijeni nemvura, simbi yegoridhe inonyungudika uye inonyungudika mu cyanide solution, zvichikonzera kuumbwa kwegold-cyanide complex. Nzira iyi inoshanda zvikuru uye yave iri tsika yekuchera goridhe nesirivha kwemakore mazhinji. Inogonesa kudzoreredzwa kwesimbi dzinokosha kubva mumatombo emhando yepasi, ayo angave asina kunaka pakugadzirisa uchishandisa dzimwe nzira. Semuenzaniso, mumigodhi mikuru yegoridhe pasi rose, sodium cyanide inoshandiswa muhuwandu hwakawanda kuburitsa goridhe. Mune mimwe migodhi yeAfrica neSouth America, zviuru zvematani esimbi zvinorapwa necyanide solutions zuva nezuva kuti zviwane goridhe shoma.

Imwe Metal Processing

Sodium cyanide inoshandiswawo mukuparadzanisa nekuchenesa dzimwe simbi dzakadai semhangura, zinc, uye nickel. Munguva iyi, cyanide inogona kusunganidza nedzimwe simbi, zvichiita kuti dziparadzaniswe netsvina kana dzimwe simbi dziri muore. Semuenzaniso, muindasitiri yemigodhi yemhangura , cyanide inogona kushandiswa kuparadzanisa mhangura nedzimwe simbi dzakabatana dziri mumuviri weore. Izvi zvinoitwa nekugadzirisa pH uye huwandu hwecyanide solution kuti ienderane nekugadzirwa kwesimbi chaiyo yecyanide.

2. Electroplating

Muindasitiri yeElectroplating , sodium cyanide chinhu chakakosha mu plating bath. Inobatsira kuisa simbi dzakadai semhangura, sirivha, cadmium, uye zinc panzvimbo dzakasiyana-siyana. Maion eCyanide mu plating solution anoshanda se complexing agents. Anogadzira complexes ne simbi ions, izvo zvinobatsira kudzora mwero wekuiswa kwesimbi. Nekuda kweizvozvo, simbi yakafanana uye inonamatira inowanikwa pamusoro pechinhu chiri kuputirwa. Semuenzaniso, mukugadzirwa kwezvishongo zvemhando yepamusoro, electroplating nesirivha kana goridhe inowanzo sanganisira kushandiswa kwe cyanide-based plating solutions. Kuvapo kwe sodium cyanide kunoita kuti simbi inokosha ichengetedzwe zvakaenzana, zvichiita kuti zvishongo zvive zvakanaka uye zvinopenya. Muindasitiri yemotokari, zvikamu zvakaita sema bumpers ne zvishongo zvekushongedza zvinowanzo putirwa ne electroplated uchishandisa cyanide-ine solutions yekuvandudza chitarisiko chazvo uye kuramba ngura.

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.
