Ukunciphisa Ukukhishwa Kwegesi Ye-Hydrogen Cyanide Ekuchithekeni Kwe-Sodium Cyanide

Isingeniso

Sodium i-cyanide ikhemikhali enobuthi obukhulu esetshenziswa kakhulu ezimbonini ezinjengezimayini, ukucubungula insimbi, kanye ne-electroplating. Lapho a i-sodium cyanide ukuchitheka kwenzeka, ukukhululwa okungenzeka kwe igesi ye-hydrogen cyanide iba ukukhathazeka okukhulu. Le gesi ibeka engcupheni enkulu empilweni yomuntu kanye nemvelo. Lokhu okuthunyelwe kwebhulogi kunikezelwe ekuhloleni amasu asebenzayo okunciphisa ukukhishwa kwegesi ye-hydrogen cyanide phakathi nezigameko ezinjalo.

Ukuqonda Ukusabela

I-sodium cyanide ingasabela ngamanzi, ama-asidi, noma ezinye izinto ukuze ikhiqize igesi ye-hydrogen cyanide. Ukusabela kuyabuyiseleka emuva, kodwa izimo ezithile, njengamanzi amaningi noma indawo ene-acidic, zingenza ibhalansi ifinyelele ekukhiqizweni kwegesi eyengeziwe.

Izinyathelo Zokuphendula Ngokushesha

Ukuphuma kanye Nokuhlukaniswa

Okubalulekile okuphezulu uma kwenzeka a I-Sodium Cyanide ukuchithwa kuwukusuka endaweni ngokushesha. Misa umjikelezo ovikelekile endaweni yokuchitheka ukuze ukhiphe abantu abangagunyaziwe. Qiniseka ukuthi abaphenduli bezimo eziphuthumayo bayaziswa futhi bahlonyiswe ngezinto ezifanele zokuzivikela (i-PPE). Lokhu kuhlanganisa imaski yegesi enezihlungi ezifanele, amagilavu ​​amelana namakhemikhali, izibuko, nezingubo zokuzivikela.

Ukuqunjelwa kokuchitheka

Iqukethe okuchithiwe I-sodium cyanide ukuvimba ukusabalala kwayo. Sebenzisa izinto ezimunca njengesihlabathi, i-vermiculite, noma ezicushiwe I-Carbon ukuze umunce uketshezi noma i-cyanide eqinile. Yakha izithiyo noma imisele ezungeze indawo echithekile ukuze uvimbele i-cyanide ukuthi ingafiki emanzini, emiseleni yamanzi, noma kwezinye izindawo ezisengozini.

Ukunciphisa Ukukhishwa Kwegesi Ye-Hydrogen Cyanide

ukupholisa

Uma ukuchitheka kwenzeka endlini, qinisekisa ukuthi kungena umoya omuhle ukuze uhlakaze igesi ye-hydrogen cyanide. Vula amafasitela neminyango ukuze kungene umoya omusha futhi uvumele igesi ukuba iphume. Ezilungiselelweni zezimboni, vula amasistimu wokungenisa umoya wemishini ukuze uthuthukise ukujikeleza komoya. Kodwa qaphela, njengoba izinhlelo zokungenisa umoya ezingafanele zingasabalalisa igesi kwezinye izindawo.

Ukungathathi hlangothi ngama-Chemical Reagents

• hydrogen peroxide: I-hydrogen peroxide iyikhemikhali evame ukusetshenziswa ukuqeda i-sodium cyanide ne-hydrogen cyanide. I-oxidize i-cyanide ibe yi-cyanate, engeyona ingozi. Ungafutha a i-hydrogen peroxide isixazululo phezu kwe-sodium cyanide echithekile kanye nendawo ezungezile ukuze kuncishiswe i-cyanide nokunciphisa amathuba okukhishwa kwegesi ye-hydrogen cyanide.

• I-Sodium Hypochlorite: I-sodium hypochlorite, eyaziwa nangokuthi i-bleach, ingasetshenziswa ukwenza i-cyanide ingabi namandla. I-oxidize i-cyanide ibe yizinto ezinobuthi obuncane. Kodwa-ke, sebenzisa ngokucophelela, njengoba ukusetshenziswa okungalungile kungaholela ekwakhekeni kwemikhiqizo eyingozi.

• I-Thiosulfate: I-Thiosulfate ingasabela nge-cyanide ukuze yakhe i-thiocyanate, engenabuthi obuncane. Lokhu kusabela kungasiza ukunciphisa umthelela wokukhishwa kwegesi ye-hydrogen cyanide.

I-Adsorption yamanzi kanye nokukhuhla

Igesi ye-hydrogen cyanide incibilika emanzini. Kwezinye izimo, ukufafaza inkungu encane yamanzi emoyeni kungasiza ukumunca igesi. Igesi ivaleleka emaconsini amanzi bese iwela phansi. Ezilungiselelweni zezimboni, ama-gas scrubber angaqashwa. Lawa madivaysi adlulisa umoya ongcolile ngoketshezi, ngokuvamile amanzi noma isixazululo samakhemikhali, ukuze asuse ukungcola njenge-hydrogen cyanide futhi anciphise ukugcwala kwawo emoyeni.

Ukuqapha kanye Nokutholwa

Hlala uqapha ikhwalithi yomoya endaweni okuchitheke kuyo igesi ye-hydrogen cyanide. Sebenzisa amathuluzi okuthola igesi njengezinzwa ze-electrochemical, izinzwa ze-infrared, noma amashubhu embala ukuze ulinganise ukugcwala kwegesi. Le datha ibalulekile ekuhloleni ukusebenza kwezinyathelo zokunciphisa nokuqinisekisa ukuphepha kwabaphendulayo kanye nomphakathi.

Ukulungiswa Kwesikhathi Eside

Uma usongo olusheshayo lokukhishwa kwegesi ye-hydrogen cyanide selulawulwa, ukulungiswa kwesikhathi eside kwendawo ethintekile kuyadingeka. Lokhu kuhilela ukususa nokulahlwa kwenhlabathi engcolile, okokusebenza okuqeda ukungcola nezindawo ezingaphezulu, kanye nokubhekisisa noma iyiphi i-cyanide esele. Umhlabathi ongcoliswe i-sodium cyanide kungase kudingeke ukuthi umbiwe, ulashwe futhi ulahlwe endaweni eyingozi.

Isiphetho

Ukunciphisa ukukhishwa kwegesi ye-hydrogen cyanide ekuchithekeni kwe-sodium cyanide kudinga impendulo esheshayo nehlelekile. Ngokusebenzisa ukuphuma ngokushesha kanye nokuvinjwa, kanye nezindlela ezisebenzayo zokungathathi hlangothi, ukungena komoya, kanye namasu okuqapha, ubungozi obulethwa igesi ye-hydrogen cyanide bungancishiswa kakhulu. Ukuqeqeshwa okufanele kwabaphenduli bezimo eziphuthumayo kanye nokusetshenziswa ngendlela efanele kwama-reagents amakhemikhali kuyisihluthulelo sokuvikela abantu nendawo ezungezile lapho kubhekwana nokuchitheka kwe-sodium cyanide.
