Maudindo ndi Kugwiritsa Ntchito Sodium Cyanide Solution

Yankho la sodium cyanide , lomwe lili ndi formula ya mankhwala ya NaCN m'madzi, ndi chinthu chofunikira kwambiri m'mafakitale ndi m'makemikolo, ngakhale kuti ndi poizoni kwambiri. Nkhaniyi ikufotokoza za ntchito zosiyanasiyana za yankho la sodium cyanide.

1. Golide ndi Zamtengo Wapatali M'zitsulo M'migodi

1.1 Kufotokozera Njira

Chimodzi mwa ntchito zodziwika bwino za sodium cyanide solution chili mumakampani opanga migodi, makamaka pochotsa golide ndi zitsulo zina zamtengo wapatali. Pamene sodium Cyanide solution ikasakanizidwa ndi miyala yamtengo wapatali, golide yemwe ali mu miyalayo amakumana ndi ma ayoni a cyanide pamaso pa mpweya wochokera mumlengalenga ndi m'madzi. Izi zimapanga golide wosungunuka - cyanide complex. Golide akangosungunuka, amatha kulekanitsidwa ndi zinthu zina zotsalazo.

1.2 Njira Zochotsera

Pali njira ziwiri zomwe zimagwiritsidwa ntchito pochotsa izi:

• Kutulutsa thanki : Mchere wa golide umayikidwa m'mathanki akuluakulu ndikusakanikirana ndi yankho la sodium cyanide . Pambuyo pa nthawi inayake, golide akasungunuka mu yankho, yankho la cyanide lomwe lagwiritsidwa ntchito pamodzi ndi miyala yotsalayo amasamutsidwira kumalo osungiramo zinthu zakale.

• Kutulutsa golide wophwanyika : Mchere wagolide wophwanyika umaunjikana m'milu, ndipo sodium cyanide solution imathiridwa pa muluwo. Pamene solution ikulowa mu muluwo, imasungunula golide. Yankho lomwe lili ndi golide wosungunuka limasonkhana pansi pa muluwo kenako limatha kusonkhanitsidwa kuti likonzedwenso kuti libwezeretse golideyo.

2. Kusintha kwamagetsi

2.1 Ntchito M'mabafa a Electroplating

Sodium cyanide solution imagwiritsidwa ntchito posambira kwa electroplating zitsulo monga mkuwa, siliva, cadmium, ndi zinki. Mu electroplating, cholinga chake ndikuyika chitsulo chochepa kwambiri chomwe mukufuna pa gawo lapansi. Ma cyanide ions mu sodium cyanide solution amagwira ntchito zingapo zofunika. Amachepetsa kuphatikizika kwa anode, kuwonetsetsa kuti anode, gwero la chitsulo chokutidwa, amasungunuka mofanana, zomwe ndizofunikira kuti ma ion azitsulo azikhala osasinthasintha. Kuphatikiza apo, kukhalapo kwa ayoni a cyanide kumathandizira kukhazikika kwa njira ya electroplating, kuteteza mvula yazinthu zachitsulo zomwe zingasokoneze plating. Zimapangitsanso polarization ya cathode, zomwe zimapangitsa kuti zitsulo zikhale zofanana kwambiri pa cathode, gawo lapansi likuphwanyidwa, zomwe zimapangitsa kuti zitsulo zikhale zosalala komanso zowonjezereka.

3. Chemical Synthesis

3.1 Kupanga kwa Inorganic Cyanides

Sodium cyanide solution ndi chinthu chofunikira kwambiri poyambira kupanga ma cyanide osiyanasiyana osapangidwa . Mwachitsanzo, cyanide imodzi yosapangidwa kuchokera ku iyo imagwiritsidwa ntchito mumakampani azakudya ngati choletsa kufalikira kwa matenda komanso popanga utoto wabuluu. Ina, ikapezeka kudzera mu reaction ndi mchere wina, imagwiritsidwa ntchito mofanana ndi sodium cyanide, monga mu njira zina zochotsera golide ndi zina zopangidwa ndi organic.

3.2 Kaphatikizidwe ka Organic Compounds

Mu organic chemistry, sodium cyanide solution imagwiritsidwa ntchito poyambitsa gulu la cyano mu mamolekyu achilengedwe, omwe ndi gawo lofunikira pakuphatikizika kwazinthu zambiri. Pamene alkyl halide imachita ndi sodium cyanide solution, pawiri imapangidwa. Pawiriyi imatha kusinthidwa kukhala magulu ena ogwira ntchito monga ma carboxylic acid ndi ma amines kudzera muzotsatira zamankhwala, kupanga njira ya sodium cyanide kukhala reagent yofunika pakuphatikizika kwa mankhwala, agrochemicals, ndi zinthu zosiyanasiyana zachilengedwe.

4. Kuyeretsa Zitsulo ndi Kusamalira Pamwamba

4.1 Kusungunula Metal Oxides ndi Zonyansa

Sodium cyanide solution ingagwiritsidwe ntchito kuyeretsa zitsulo. Ma oxides ena achitsulo ndi zonyansa pamwamba pa zitsulo zimatha kuchitapo kanthu ndi ayoni a cyanide. Mwachitsanzo, copper oxide pamwamba pa mkuwa amatha kuchitapo kanthu ndi sodium cyanide solution pansi pazifukwa zina. Ma cyanide ions amapanga ma complexes ndi ayoni azitsulo kuchokera ku oxides, kuchotsa bwino chigawo cha oxide ndikusiya chitsulo choyera. Izi ndizothandiza pokonzekera zitsulo kuti zipitirire kukonzanso monga kujambula, soldering, kapena electroplating.

5. Kuwononga Tizirombo (Zochepa komanso Zolamulidwa Kwambiri)

5.1 Gwiritsani ntchito ngati Rodenticide

M'mbuyomu, sodium cyanide solution idagwiritsidwa ntchito ngati rodenticide. Kuopsa kwake kumapangitsa kukhala koopsa kwa makoswe. Komabe, chifukwa cha kawopsedwe kake koopsa osati kwa tizirombo tokha komanso kwa zamoyo zomwe sizingawonongedwe, kuphatikiza anthu, kugwiritsa ntchito kwake ngati mankhwala ophera makoswe kwaletsedwa kwambiri m'maiko ambiri. Chiwopsezo chowonekera mwangozi komanso kuthekera kwa kuipitsidwa kwa chilengedwe ndizovuta zazikulu zomwe zimagwirizanitsidwa ndi kugwiritsidwa ntchito kwake polimbana ndi tizilombo.

Zilingaliro Za Chitetezo

Ndikofunikira kwambiri kudziwa kuti sodium cyanide solution ndi poizoni kwambiri. Ngakhale pang'ono pang'ono akhoza kupha munthu ngati atalowetsedwa, atakoka mpweya, kapena atalowa pakhungu. Ikakumana ndi zidulo kapena mpweya wonyowa, imatha kutulutsa mpweya wapoizoni wa hydrogen cyanide. Chifukwa chake, njira zotetezera zolimba ziyenera kutsatiridwa pogwira yankho la sodium cyanide. Ogwira nawo ntchito ayenera kuphunzitsidwa bwino, kuvala zida zodzitetezera zoyenera, ndi kugwira ntchito m'malo opumira mpweya wabwino. Zikatayika mwangozi kapena zowonekera, njira zoyankhira mwadzidzidzi ziyenera kutsatiridwa kuti zipewe kuwonongeka kwakukulu kwa thanzi la anthu komanso chilengedwe.

Pomaliza, yankho la sodium cyanide, ngakhale kuti ndi lowopsa, limagwira ntchito yofunika m'mafakitale angapo. Ntchito zake zimachokera ku chitsulo chamtengo wapatali kupita ku kaphatikizidwe ka mankhwala ndi chithandizo chachitsulo. Komabe, zoopsa zomwe zimakhudzidwa zimafunikira kuti kugwiritsidwa ntchito kwake kuyendetsedwe mosamala ndikuwongolera kuti zitsimikizire chitetezo.
