tšepe tse peli tsa sulfide

Iron Two Sulfide: Tataiso e FeletsengIron two sulfide, e tsejoang hape e le ferrous sulfide, ke motsoako oa lik'hemik'hale o nang le foromo ea FeS. Tataiso ena e fana ka kakaretso e felletseng ea thepa ea eona, motsoako, lits'ebetso, le lintlha tsa polokeho.

Thepa ea Iron Two Sulfidi

Iron sulfide tse peli e teng ka mefuta e mengata ea kristale, e tloaelehileng haholo ke mineral pyrrhotite ea tlhaho. Hangata diminerale ena e bontša sebopeho se seng sa stoichiometric, ho bolelang hore karo-karolelano ea tšepe le sebabole e ka fapana hanyenyane. Hloekileng tšepe tse peli tsa sulfide e boputsoa bo lefifi ho isa ho botsho bo tiileng. E batla e sa qhibilihe ka metsing empa e kopana le asiti ho hlahisa khase ea hydrogen sulfide, ntho e chefo e matla le e ka chang. Sebaka sa eona sa ho qhibiliha se batla se phahame, hoo e ka bang 1195 °C (2183 °F).

Lintho tsa Lik'hemik'hale

Iron sulfide tse peli e arabela habonolo ka li-acids, joalo ka hydrochloric acid (HCl), ho hlahisa khase ea hydrogen sulfide (H?S):FeS(s) + 2HCl(aq) → FeCl?(aq) + H?S(g)Karabelo ena e atisa ho sebelisoa ha ho etsoa laboratoring ea hydrogen sulfide. Karabelo ea oksijene e ka boela ea etsahala, e lebisang ho thehoeng ha li-oxide tsa tšepe le sulfur dioxide.

Synthesis ea Iron Two Sulfide

Iron sulfide tse peli e ka kopanngoa ka mekhoa e mengata. Mokhoa o tloaelehileng o kenyelletsa tšepe e sebetsanang le sebabole ka ho toba mochesong o phahameng:Fe(li) + S(s) → FeS(s)Karabelo ena e chesa haholo 'me e hloka taolo e hlokolosi ho thibela ho futhumatsa ho sa laoleheng. Mokhoa o mong o kenyelletsa karabelo ea pula lipakeng tsa tšepe e qhibilihang(II) letsoai le letsoai le qhibilihang sulfide:FeCl?(aq) + Na?S(aq) → FeS(s) + 2NaCl(aq)Mokhoa ona o fana ka pula tšepe tse peli tsa sulfide eo ka nako eo e ka tlhotliloeng le ho omisoa.

Lisebelisoa tsa Iron Two Sulfidi

Iron sulfide tse peli e fumana lisebelisoa liindastering tse fapaneng. Tšebeliso e 'ngoe ea bohlokoa ke tlhahisong ea khase ea hydrogen sulfide, e sebelisoang lits'ebetsong tse fapaneng tsa indasteri le joalo ka sehlahisoa sa ho kopanya lik'hemik'hale. E boetse e na le seabo ho metallurgy ea tšepe le tšepe, e sebetsa e le mohloli oa sebabole. Ho feta moo, ke karolo ea li-pigment tse ling. Leha ho le joalo, ka lebaka la chefo ea likhase tseo e ka li hlahisang, tšebeliso ea eona e hloka mehato e matla ea tšireletso.

Mehopolo ea Tšireletseho

Ho bohlokoa ho sebetsana tšepe tse peli tsa sulfide ka hloko ka lebaka la bokhoni ba eona ba ho sebetsana le asiti ho hlahisa khase ea hydrogen sulfide e chefo haholo. Lisebelisoa tse loketseng tsa ho itšireletsa (PPE), tse kang liatlana, tšireletso ea mahlo, le tšireletso ea phefumoloho, li lokela ho sebelisoa kamehla ha ho tšoaroa motsoako ona. Ho hlokahala moea o lekaneng ho thibela ho bokellana ha likhase tse chefo. Haeba motho a ka pepeseha, ho lokela ho batloa tlhokomelo ea meriana hang-hang.
