Imbali, iEvolution, kunye neSimo sangoku seSodium Cyanide

intshayelelo

Sodium i-cyanide (I-NaCN), ityuwa ye-inorganic enetyhefu kakhulu, idlale indima ebalulekileyo kumashishini ukusuka kwimigodi ukuya kwi-pharmaceuticals. Eli nqaku lilandelela iingcambu zalo zembali, liphonononga indaleko yalo kwezoshishino, kwaye liphonononga indawo yalo yangoku kwixesha eligxile ekuzinzeni.

1. Imvelaphi yembali

Isodium cyanide yaqala ukwenziwa phakathi kwinkulungwane ye-19, ekuqaleni yafumana ukuduma njengesixhobo sokwenza izinto. ukulungiswa kwesinyithi kunye nokutsalwa. Impumelelo yayo yeza kwicandelo lemigodi yegolide, apho yaba yimfuneko ekwahluleni igolide nesilivere kwintsimbi ekrwada inkqubo ye-cyanidation.

Ngasekupheleni kwee-1800s, ushishino lwandise ukusetyenziswa kwalo ukuya kuthi ga:

• Ukuveliswa kwedayi

• Ukwenziwa kwerabha yokwenziwa

• Uphuhliso lwezitshabalalisi

  
  

  
  

2. 20th-Century Evolution

Nakuba Isodium cyanideUbutyhefu bufune imithetho engqongqo yokhuseleko, ukusetyenziswa kwayo kuqhubele phambili ukwamkelwa okubanzi:

Izicelo eziphambili

1. Imigodi: Kushiyeke iyeyona meko iphambili yokusetyenziswa kokutsalwa kwegolide, okubangela ukuchacha okusebenzayo komgangatho ophantsi okrwada.

2. Chemistry Chemistry: Isebenza njenge-catalyst okanye ephakathi kwiimpendulo ezifana ne-nitrile synthesis.

3. Pharmaceuticals: Isetyenziselwa ukuveliswa kwamachiza afana ne-acetazolamide (i-diuretic).

Iinkxalabo zoLawulo ziyavela

Ukukhula kolwazi malunga nemingcipheko yendalo esingqongileyo kunye nempilo kukhokelele ekubeni:

• Mthetho: Amazwe afana ne-US neKhanada anyanzelise imigaqo engqongqo yokugcina, ukuthutha, kunye nokulahlwa.

• Imigangatho yoshishino: Ukwamkelwa kwezikhokelo zokhuseleko ukuze kuncitshiswe ukuba sesichengeni ngengozi.

3. Imbonakalo-mhlaba yangoku (kwiNkulungwane yama-21)

namhlanje, sodium cyanide's indima ibunjwe ngu uzinzo iinjongo kunye nokwenziwa ngokutsha kwetekhnoloji:

1. IiTekhnoloji ezizezinye

• Green Mining: Uphando kwizinto ezingenayo ityhefu (umzekelo, i-thiosulfate leaching) ijolise ekunciphiseni ukuthembela kwi-cyanide.

• IiNdlela eziNgcono eziBonekalisiweyo: Uphuhliso lwe-eco-friendly chelating agents ukwenzela ukutsalwa kwesinyithi.

2. Imigaqo engqongqo

• Ukuthobela umhlaba: Amazwe anyanzelisa i-ISO 14001 kunye nemigangatho efana ne-REACH ukuthomalalisa ukwenzakala kokusingqongileyo.

• Ukulandelela iDijithali: Izixhobo zeBlockchain kunye ne-IoT ziphucula ukucaca kokubonelela.

3. Uphando kunye neMfundo

• Uqeqesho ngokhuseleko: Iinkqubo ezinyanzelekileyo zabasebenzi bamashishini abaphatha i-NaCN.

• Amalinge eMfundo: Iidyunivesithi zisebenzisana namashishini ukujonga iindlela ezikhuselekileyo zokudibanisa.

isiphelo

Ukusukela ekufumaneni kwayo ngenkulungwane ye-19 ukuya kwizicelo zayo zale mihla, Isodium cyanide Ihlala ingumnqa: isixhobo esibalulekileyo semizi-mveliso esinomngcipheko wendalo. Ngelixa iindlela ezizezinye kunye nemigaqo izama ukunciphisa indawo yayo ye-ikholoji, indima yayo engenakubuyiselwa kumacandelo afana nemigodi iqinisekisa ukusetyenziswa kwayo okuqhubekayo-nangona kugxilwe kakhulu kukhuseleko kunye nozinzo.
