Kumvetsetsa ndi kugwiritsa ntchito Fe II sulfide

Buku lokwanirali limayang'ana katundu, ntchito, ndi tanthauzo laFeI ii sulfide(iiro (ii) sulfide). Timacheza m'njira zosiyanasiyana, njira zosiyanasiyana, komanso kugwiritsa ntchito mafakitale, ndikugwiritsa ntchito mwatsatanetsatane kwa ofufuza, ophunzira, ndi akatswiri ofanana. Dziwani za gawo lake m'minda yosiyanasiyana ndikumvetsetsa kufunikira kwake kofunikira mu njira zingapo zasayansi ndi mafakitale.

Mafomu ndi katundu wa Fe II sulfide

Chitsulo (ii) sulfide: gawo losiyanasiyana

FeI ii sulfideilipo m'mitundu ingapo ya crystalline, iliyonse yokhala ndi zinthu zosiyana. Mitundu yodziwika kwambiri imaphatikizapo Troilite (FES), Macchonawa (Fe_1-xS), ndi purrhotete (Fe_1-xS). Troilite, mchere wa hexiloral, umapezeka nthawi zambiri mwa meteorites. Maculowawu, mchere wa tetragoneal, umadziwika ndi ma clowers otsika ndipo nthawi zambiri amawonedwa m'malo okhala. Purrhotite, mchere wokhala ndi zitsulo zosiyanasiyana, zimawonetsa magulu osiyanasiyana a kristalo ndi maginito. Zinthu zenizeni zaFeI ii sulfidekudalira kwambiri mawonekedwe ake ndi oyera.

Mfunguyi ndi mankhwala

Katundu waFeI ii sulfidezimasiyana malinga ndi polymorph yake. Komabe, madera ena amaphatikizapo mtundu wake wamdima (kuyambira brownish-wakuda kupita ku imvi-wakuda), kachulukidwe kake kakang'ono, ndipo chiwopsezo chake ndi oxidation. Mankhwala, amadziwika kuti amagwira ndi acid, amapanga hydrogen sulfide gasi (H₂S), chinthu chopondera komanso choyipa. Kuzindikira malo awa ndikofunikira pakugwira ntchito moyenera komanso kugwiritsa ntchito.

Kapangidwe kake ndi kupanga kwa Fe II sulfide

Njira za Laboratory Synthesis

FeI ii sulfideikhoza kupangidwa mu labotale kudzera njira zingapo. Njira yodziwika bwino imathandizira kuti azigwiritsa ntchito mchere (monga chitsulo (monga chitsulo (ii) chloride) ndi gwero la sulfide (monga sodium sulfide). Zomwe zimayambitsa zimatulutsaFeI ii sulfide, zomwe zitha kuyeretsedwa ndikudziwika. Njira zina zimaphatikizapo kusintha kwamphamvu kwambiri kapena kaphatikizidwe ka hydrothermal.

Kupanga mafakitale ndi magwero

Mosangalala,FeI ii sulfideNthawi zambiri imapezeka ngati yosiyanasiyana kapena yochokera ku zolengedwa zachilengedwe ngati sulfide ores. Mwachitsanzo, ndi gawo wamba pokonza nickel ndi o ores. Mongolia Xinxin Silicon Makampani co., ltd (https://www.xinxinsIciicilicial.com/) Chitsanzo chodziwika bwino cha kampani yotenga nawo mbali yopanga michere yosiyanasiyana, akuwonetsa kufunikira kwa kumvetsetsa izi mkati mwapafupipafupi kwa michere ya mchere.

Ntchito za Fe II sulfide

Ntchito za Mafakitale

FeI ii sulfideamapeza mapulogalamu m'mafakitale osiyanasiyana. Imagwira ntchito ngati chotsogola popanga zitsulo zopangidwa ndi chitsulo ndipo zimagwiritsidwa ntchito popanga zina mwazinthu zina. Imathandizanso mitundu ina yachitsulo. Kugwiritsa ntchito kwenikweni kumadalira kwambiri mawonekedwe ndi kuyera kwaFeI ii sulfide.

Mapulogalamu asayansi ndi kafukufuku

Pa kafukufuku wasayansi,FeI ii sulfideamagwiritsidwa ntchito kwambiri mu maphunziro a geochemistry, zida za sayansi, ndi umisala wa chilengedwe. Kukhalapo kwake m'njira zosiyanasiyana, gawo lake m'magazini a biogebocmical, ndipo maginito ake amapangitsa kuti ikhale yofufuzira.

Maganizo a chitetezo

Kusamalira ndi Kusunga

Ndikofunikira kugwiraFeI ii sulfideMosamala chifukwa cha kuthetsedwa kwa poizoni ndi kuyaka kwa mpweya wa hydrogen pochita ndi asidi kapena chinyezi. Mpweya wabwino komanso zida zoteteza (PPE) ndizofunikira mukamagwira ntchito ndi izi.

Mphamvu ya chilengedwe

Chilengedwe chaFeI ii sulfidendizovuta ndipo zimatengera mawonekedwe ake komanso nkhani yake. Udindo wake mu kuzungulira kwa sulfur komanso kuthekera kwake kupanga ma acidi a asidi ndi zofunika kuzilingalira.

Mapeto

FeI ii sulfide, ngakhale anali ndi mtundu wosavuta wamankhwala wowoneka bwino, ndi gawo losiyanasiyana molingana ndi zofunikira kwambiri m'minda yasayansi ndi mafakitale. Nkhaniyi ikupereka mwachidule mafomudwe ake osiyanasiyana, katundu wake njira, njira, njira, ndi malingaliro achitetezo. Kafukufuku wina m'zinthu zomwe zimagwiritsidwa ntchito ndi polymorph iliyonse yaFeI ii sulfideipitiliza kuwulula zovuta zake komanso kufunikira.

¹Zambiri zokhudzana ndi njira zapadera za mafakitale ndi ntchito nthawi zambiri zimapezeka pamabuku a sayansi komanso mafakitale. Nthawi zonse funsani ma sheet a deta yachitetezo (SDS) musanayambe kugwiritsa ntchito mankhwala.
