Sodium Cyanide: Mashandisirwo Akakosha muMigodhi uye Kupfuura

Sodium Cyanide ine Toxic sei?

Sodium cyanide icrystalline poda chena kana magranules ari hygroscopic uye ane kufenda kunhuhwirira kwearumondi. Inonyungudika zvakanyanya mumvura uye inokurumidza kuita hydrolyze kuumba hydrogen cyanide, nemushonga wayo une aqueous uri alkaline yakasimba. Chinhu chakakosha chemakemikari mbishi zvinhu. Zvinonyanya kukosha, ine muchetura zvakanyanya; kubata nemaronda eganda, kufemera pamusoro, kana kupinza chero chidimbu chidiki kunogona kukonzera chepfu uye kufa.

Uchishandisa iyo inowanzotaurwa LD50 (iyo dose inodiwa kuuraya hafu yemhuka dzekuedzwa mukati menguva yakatarwa), arsenic ine LD50 ye14.6 mg/kg (mumuromo mumakonzo), nepo. Sodium cyanide ine LD50 ye6.44 mg/kg (mumuromo mumakonzo). Izvi zvinoreva kuti Sodium Cyanide ine simba rakapetwa katatu pane arsenic.

Chinotonyanya kutyisa inyaya yekuti izvi zvine chepfu zvakanyanya cyanides kunyungudika nyore mumvura, zvichiita kuti kukurumidza migumisiro. Rufu runogona kuitika mukati memaminitsi e15 kusvika kuawa ye1, zvichisiya vashandi vezvokurapa vane nguva shoma yekununura. Mukuenzanisa, arsenic inoita zvishoma nezvishoma; zviratidzo zvingasaonekwa kusvikira awa imwe mushure mekudya, uye rufu runogona kuitika maawa akawanda kana kunyange zuva gare gare.

Kushandiswa kwemaindasitiri eSodium cyanide

Mumakore achangopfuura, zvikumbiro zve sodium cyanide zvawedzera kupararira. Parizvino, kushandiswa kwesodium cyanide inonyanya kushandiswa kwemakemikari, inoverengera inenge 40% yemugove wemusika; chikamu chemishonga chinotora chikamu che10%; mishonga yezvipembenene inosvika 8%; uye electroplating indasitiri inoita 20%. Kushandiswa kwasara kuri mumakemikari akanaka. Mumakore achangopfuura, nekukura kuri kuda kwegoridhe, kudiwa kwe sodium cyanide mumigodhi kwakawedzera zvakanyanya. Semuenzaniso, muna 2013. kutengeswa kwesodium cyanide yakashandiswa kuburitsa goridhe yaive 2 kusvika 3 nguva ye2012. uye musika wemishonga yezvipembenene wakaonawo kuwedzera, kunyanya kune glyphosate nezvimwe zvakafanana zvigadzirwa.

1. Dhayi

Sodium cyanide inogona kushandiswa kugadzira dhayi. Madhayi anogona kugadzirwa parizvino anosanganisira Yero 139. Yero 150. indigo, brilliant blue, fluorescent whitening agent VBL, uye Disperse Green GL, pakati pezvimwe.

2. Mishonga

Sodium cyanide inogona kushandiswa kugadzira mishonga yepakati, ichipa zvakakosha zvigadzirwa zvekupedzisira zvigadzirwa zvemishonga. Mishonga yakajairika inosanganisira penicillin, pregabalin, ketoprofen, tranexamic acid, vhitamini B6. folic acid, guanine, acyclovir, gabapentin, butyrophenone, barbiturates, fluoroquinolones, caffeine, zvinoderedza chikosoro, gastric mishonga, analgesics, berberine, atorvastatin, uye phenylpropanolamine.

3. Mishonga yezvipembenene

Sodium cyanide inogona kushandiswa kugadzira mishonga yezvipembenene, iyo inoshandiswa zvakanyanya kune zvirimwa nemiriwo. Mishonga yezvipembenene yakajairika inosanganisira glyphosate, cypermethrin, paraquat, cyantraniliprole, sulfentrazone, pyraclostrobin, benzoylpropionic acid, oxime esters, atrazine, cyanazine, uye zvakasiyana-siyana zvekudzivirira zvirwere zvemupunga.

4. Electroplating

Sodium cyanide inogona kuumba macomplexes ane simbi dzakawanda, ichiita kuti inowanzoshandiswa muindasitiri ye electroplating se electrolyte yemhangura, cadmium, zingi, uye sirivheri. Iyo simbi ion complexes mune idzi electrolytes inogona kuisa pamusoro pezvishandiso, ichigadzira firimu rakatetepa rinodzivirira zvigadzirwa zvesimbi.

5. Madini

Sodium cyanide inokwanisa kunyungudutsa goridhe nesirivheri, ichiita soluble cyanide complexes, ndosaka ichishandiswa mukuchera goridhe, sirivheri, uye simbi dzisina ferrous. Mumigodhi yegoridhe yepasi-giredhi, yakawanda yakacherwa goridhe inoitwa pachishandiswa nzira ye "heap leaching" ine sodium cyanide. Iyi nzira yekubvisa ine yakakosha mutengo mukana. Nzira ye "heap leaching" inosanganisira kumwaya mushonga we sodium cyanide pamurwi wematombo, zvichiita kuti zvinhu zvinenge zvanangwa zvinyunguduke mumugadziro, kubva ipapo goridhe rinobva ratorwa. Nyangwe Cyanides zvinozivikanwa seanoshanda goridhe leaching agents, hunhu hwavo hwehupfu hunomutsa kunetseka, uye tsvina yecyanide inogona kukuvadza zvakanyanya nharaunda. Naizvozvo, nzira dzakasiyana siyana, dzinosanganisira chlorination, acidification, uye activated kabhoni adsorption catalytic oxidation, dzinoshandiswa muChina kurapwa kwecyanide tailings. Maitiro akanakisa ekuchera goridhe anosanganisira kushandisa cyanide-isina uye yakaderera-cyanide dzimwe nzira.

6. Zvimwe Zvishandiso

Pamusoro pezvishandiso zviri pamusoro, sodium cyanide inogona zvakare kushandiswa kugadzira amino acids, L-carnitine, lactic acid, creatine, chelating agents, cyanate esters, UV absorbers, light stabilizers, uye zvinonhuhwirira, pakati pezvimwe zvigadzirwa zvemakemikari.

Sodium cyanide, vanhu vangazvidzivirira sei?

Chinonyanya kukosha ndechekuti:vanhu vari kunze vanofanira kubuda kuenda kunzvimbo inokwana makiromita maviri kubva panzvimbo yetsaona uye kuvhuvhuta nemhepo kudzivirira kubata chero chinhu chemakemikari.

Ganda kuonana:Kurumidza bvisa zvipfeko zvakasvibiswa uye nyatsosuka nzvimbo yakakanganiswa nemvura inoyerera kana 5% sodium thiosulfate solution kwemaminitsi makumi maviri. Enda kurapwa nokukurumidza.

Kutarisana kwemaziso:Pakarepo sukurudza maziso nemvura yakawanda inoyerera kana saline solution kwemaminitsi gumi nemashanu. Enda kurapwa nokukurumidza.

Inhalation: Kurumidza kusiya chiitiko uchienda kunzvimbo ine mhepo yakachena. Kana matambudziko ekufema akaitika, ipa oxygen. Kana kufema uye kurova kwemwoyo zvikamira, pakarepo ita kufema kwemaitiro (usashandise muromo-ku-muromo) uye kudzvanya chipfuva.

Kuisa: Inwa mvura inodziya yakakwana kuti urutse. Shandisa 1:5000 potassium permanganate solution kana 5% sodium thiosulfate solution yegastric lavage. Enda kurapwa nokukurumidza.

Mazano Anodziya: Kana iwe uchida kuziva rumwe ruzivo, senge quotation, zvigadzirwa, mhinduro, nezvimwe.
