icyuma cya sulfide

Iron Iron Sulfide: Ubuyobozi BwuzuyeIron sulfide ebyiri, izwi kandi nka ferrous sulfide, ni imiti ivanze na formula ya FeS. Aka gatabo gatanga ishusho rusange yimiterere yacyo, synthesis, porogaramu, hamwe nibitekerezo byumutekano.

Ibyiza bya Iron Sulfide

Icyuma cya sulfide ebyiri ibaho muburyo butandukanye bwa kristalline, ibisanzwe ni ibisanzwe bisanzwe minerval pyrrhotite. Iyi minerval ikunze kwerekana ibintu bitari stoichiometric, bivuze ko igipimo cyicyuma na sulferi gishobora gutandukana gato. Byera icyuma cya sulfide ni umukara wijimye kugeza umukara ukomeye. Ntishobora gushonga mumazi ariko ikorana na acide kugirango itange gaze ya hydrogen sulfide, ibintu bifite ubumara bukabije kandi bwaka. Ahantu ho gushonga ni hejuru, hafi 1195 ° C (2183 ° F).

Ibintu bifatika

| Umutungo | Agaciro || ----------------- | --------------------------------------- || Imiti yimiti | FeS || Misa ya misa | 87,91 g / mol || Ubucucike | 4.7-5.0 g / cm3 || Ingingo yo gushonga | 1195 ° C (2183 ° F) || Kugaragara | Icyatsi cyijimye kugeza umukara kristaline ikomeye |

Ibikoresho bya Shimi

Icyuma cya sulfide ebyiri byoroshye gufata aside, nka aside hydrochloric (HCl), kugirango itange gaze ya hydrogen sulfide (H? S): FeS (s) + 2HCl (aq) → FeCl? (aq) + H? S (g) Iyi reaction ikoreshwa kenshi mugutegura laboratoire ya hydrogen sulfide. Imyitwarire hamwe na ogisijeni irashobora kandi kubaho, bigatuma habaho okiside ya fer na dioxyde de sulfure.

Synthesis yicyuma Sulfide ebyiri

Icyuma cya sulfide ebyiri Birashobora guhuzwa binyuze muburyo butandukanye. Uburyo busanzwe bukubiyemo gufata ibyuma hamwe na sulfure mu bushyuhe bwo hejuru: Fe (s) + S (s) → FeS (s) Iyi reaction irakabije kandi isaba kugenzura neza kugirango wirinde ubushyuhe butagenzuwe. Ubundi buryo bukubiyemo imvura igwa hagati yumunyu wa elegitoronike (II) n'umunyu wa sulfide ushonga: FeCl? (Aq) + Na? S (aq) → FeS (s) + 2NaCl (aq) Ubu buryo butanga imvura igwa icyuma cya sulfide zishobora noneho kuyungurura no gukama.

Gushyira mu bikorwa ibyuma bibiri bya sulfide

Icyuma cya sulfide ebyiri ibona porogaramu mu nganda zitandukanye. Ikintu kimwe cyingenzi gisabwa ni mugukora gaze ya hydrogen sulfide, ikoreshwa mubikorwa bitandukanye byinganda kandi nka reagent muri synthesis. Ifite kandi uruhare muri metallurgie yicyuma nicyuma, ikora nkisoko ya sufuru. Byongeye kandi, ni igice mubice bimwe. Ariko, kubera uburozi bwa gaze ishobora kubyara, imikoreshereze yayo isaba ingamba zikomeye z'umutekano.

Ibitekerezo byumutekano

Ni ngombwa kubyitwaramo icyuma cya sulfide ubwitonzi bitewe nubushobozi bwayo bwo gukora hamwe na acide kugirango itange gaze ya hydrogène sulfide ifite ubumara bukabije. Ibikoresho bikwiye byo kurinda umuntu (PPE), nka gants, kurinda amaso, no kurinda ubuhumekero, bigomba guhora bikoreshwa mugihe ukoresha iki kigo. Guhumeka bihagije ni ngombwa kugirango hirindwe imyuka yubumara. Mugihe hagaragaye, hakwiye gushakishwa ubuvuzi bwihuse.

Ubundi bushakashatsi

Kubindi bisobanuro birambuye kumiterere, synthesis, hamwe na progaramu ya icyuma cya sulfide, baza ubuvanganzo bwa siyansi nububiko nkubwahawe n'ikigo cy'igihugu gishinzwe ubuziranenge n'ikoranabuhanga (NIST) https://www.nist.gov/. Wibuke ko uburyo bwo gufata neza umutekano nibyingenzi mugihe ukorana niyi miti.
