Iyo Nhoroondo, Evolution, uye Mazuva Ano Mamiriro eSodium Cyanide

ziviso

Sodium cyanide (NaCN), munyu une chepfu yakawanda, wave nebasa guru mumaindasitiri akasiyana-siyana kubva kumigodhi kusvika kumishonga. Chinyorwa chino chinotsvaga midzi yawo yekare, chinoongorora kushanduka kwayo mumaindasitiri, uye chinoongorora nzvimbo yayo yazvino munguva ino inotarisa kuchengetedzeka kwezvinhu.

1. Mavambo Enhoroondo

Sodium cyanide yakatanga kugadzirwa pakati pezana remakore rechi19, ichitanga kuzivikanwa semushonga wekugadzirisa nekubvisa simbi . Kubudirira kwayo kwakauya muchikamu chekuchera goridhe, uko kwakava chinhu chakakosha pakuparadzanisa goridhe nesirivha kubva mumatombo kuburikidza nekuita cyanidation.

Pakupera kwema1800, indasitiri yakawedzera kushandiswa kwayo kusvika:

• Kugadzirwa kwedhayi

• Synthetic rubber kugadzira

• Kugadzirwa kwemishonga yezvipembenene

  
  

  
  

2. 20th-Century Evolution

Kunyange hazvo kuchetura kweSodium Cyanide kwakaita kuti pave nemitemo yakasimba yekuchengetedza, kushandiswa kwayo kwakaita kuti vanhu vakawanda vashandise:

Maitiro Ekushandisa

1. Kuchera : Yakaramba iri nzira huru yekushandisa goridhe, zvichiita kuti goridhe ridzoke zvakanaka kubva mumatombo asina kunyanya kukosha.

2. Kemikari yeOrganic : Inoshanda sechinhu chinobatsira kana kuti chinosimudzira mashandiro akaita sekugadzira nitrile.

3. Mishonga : Inoshandiswa mukugadzira mishonga yakaita seacetazolamide (inobvisa mvura mumuviri).

Regulatory Concerts Emerge

Kuwedzera kuziva nezvezvakatipoteredza uye hutano njodzi kwakatungamira kune:

• Mitemo : Nyika dzakadai seUS neCanada dzakaisa mitemo yakaoma pakuchengetedza, kutakurwa, uye kuraswa kwezvinhu.

• Mitemo yeIndasitiri : Kushandiswa kwehurongwa hwekuchengetedza kuderedza kusangana netsaona.

3. Nzvimbo Yazvino (21st Century)

Nhasi, basa re sodium cyanide rinoumbwa nezvinangwa zvekuchengetedza nharaunda uye hunyanzvi hwetekinoroji:

1. Alternative Technologies

• Kuchera Zvinyoro : Tsvagiridzo yezvinhu zvisina chepfu zvinotsiva (semuenzaniso, thiosulfate leaching) ine chinangwa chekuderedza kuvimba necyanide.

• Zvimwe Zvinogona Kuora : Kugadzira zvinhu zvinobvisa simbi zvisina njodzi pakuchengetedza nharaunda.

2. Mitemo Yakasimba

• Kutevedzera Mutemo Wepasi Pose : Nyika dzinoshandisa ISO 14001 neREACH-sequences kuderedza kukuvara kwezvakatipoteredza.

• Kutevera kweDigital : Zvishandiso zveBlockchain neIoT zvinovandudza kujeka kwecheni yekugovera.

3. Tsvakurudzo uye Dzidzo

• Kudzidziswa Kuchengetedzeka : Zvirongwa zvinosungirwa vashandi vemaindasitiri vanobata NaCN.

• Zvirongwa Zvedzidzo : Mayunivhesiti anoshanda pamwe chete nemaindasitiri kuti vaongorore nzira dzakachengeteka dzekugadzira zvinhu.

mhedziso

Kubva pakuwanikwa kwayo muzana remakore rechi19 kusvika pakushandiswa kwayo kwemazuva ano, Sodium cyanide ichiri chinhu chinoshamisa: chishandiso chakakosha chemaindasitiri chine njodzi dzayo. Kunyange hazvo dzimwe nzira nemitemo zvichiedza kuderedza kukanganiswa kwayo nezvakatipoteredza, basa rayo risingatsiviwi muzvikamu zvakaita semigodhi rinovimbisa kuti icharamba ichishandiswa—kunyangwe ichinyanya kutarisa kuchengetedzeka uye kugara kwenguva refu.
