Ferrous sulfate: physico-sinadaran Properties, da shirye-shiryen, da aikace-aikacen

Ferrous sulfate - a sinadaran fili cewa shi ne musamman tartsatsi a cikin yanayi da ake amfani da ko'ina a daban-daban duniyoyin da tattalin arziki aiki. Akwai ferric gyara daga cikin abu. Nau'i na farko, kuma aka sani da baƙin ƙarfe sulfate, a binary ba maras tabbas inorganic fili da ciwon dabara FeSO _4. Outwardly, wannan sinadaran fili ne m crystalline hydrates haske greenish-blue color ciwon babban mataki na hygroscopicity da solubility a mai ruwa-ruwa kafofin watsa labarai. A FeSO ₄ vacuo bazu tare da wani babban tsanani cikakken bazuwar auku a zazzabi na game da 700 ° C.

Divalent baƙin ƙarfe sulphate ne yadu amfani reagent a dakin da zazzabi for crystallising daga mafita kamar yadda heptahydrate FeSO ₄ ∙ 7H ₂ Ya, wanda shi ne wani abu kodadde blue color. Ga dogon lokaci ajiya shi vuya, zama wani farin powdery abu, wani waje a hankali ya jũya rawaya saboda oxidative tafiyar matakai. Weathering na ferrous sulfate da aka bayyana ta da cewa da tsarin ne ba a cikin daya kwayoyin outersphere na ruwa wanda ya fita daga crystal raga sauƙi.

Trivalent anhydrous ferric sulfate ne mai haske rawaya, paramagnetic, musamman hygroscopic crystalline abu na monoclinic crystal tsarin. Iya kafa orthorhombic da kyakkyawan tsarin gyare-gyare. Trivalent baƙin ƙarfe sulfate crystallizes da kyau daga wani iri-iri mafita a da dama hydrated mahadi dauke da har zuwa goma ruwa kwayoyin. A m dumama ne tuba zuwa cikin anhydrous gishiri, wanda yana da kyau bazu cikin hematite da sulfur anhydrite a zazzabi na game da 650 ° C. Kamar sauran salts na triply cajin cations, ferrous sulfate siffofin alum, wanda crystallize a cikin wani nau'i na kodadde Violet octahedra. Wannan abu ne mai kyau rage wakili ga ions Ag +, da ciwon karfi oxidizing Properties. Trivalent ferric sulfate hydrolysis abin da ya auku da refluxing da mafita a cikin abin da yake kunshe, wanzu a yanayi, yafi a cikin jarosite (ma'adinai).

A masana'antu, da abu da aka shirya da gaske a matsayin gefen samfurin a cikin metalworking shuke-shuke daga daban-daban etchants amfani da su cire sikelin daga karfe kayayyakin. Har ila yau, wannan abu iya ware ta ƙõnuwa pyrites ko marcasites da NaCl a iska. Wani Hanyar kira shi ne dumama baƙin ƙarfe oxide a salts da sulfuric acid. A dakin gwaje-gwaje yi, da fili da aka ware daga Fe (OH) _2.

Babba son sani shi ne gaskiya cewa ferrous sulfate aka gano a duniyar Mars, a 2009. A kumbon sama jannati "Ruhu", daga abin da masu bincike ƙarasa da cewa da ya kwarara a kan surface karfi hadawan abu da iskar shaka tafiyar matakai. Saboda sosai low yawa daga cikin abu Rover haka warai mired a adibas, cewa ko da sashi na jiki shãfe cikin zurfin yadudduka na Martian gona.

A duniya, ferric sulfate saboda da ikon hydrolyze tare da Alum aka yi amfani a matsayin flocculant a kan aiwatar da tsarkakewa daga shan ruwa. Ulla flakes hydroxide, a sinadaran fili adsorbs yawa gurɓatawa. Har ila yau, wannan abu ne yadu amfani a magani, inda amfani da wani warkewa da kuma prophylactic wakili don baƙin ƙarfe rashi anemia.

A cikin aikin noma, masana'antu da baƙin ƙarfe sulfate amfani da sunadarai ƙasa kyautata, kwaro iko da amfanin gona, a halaka mosses, lichens, weeds da spores na parasitic fungi. A noma, ferrous sulfate da ake amfani da barbarar 'ya'yan itatuwa kamar yadda mai kara kuzari chlorophyll samuwar tsari. Mai kula da rashin wannan abu ne apple, pear, plum da peach.

A masana'antu, ferrous sulfate ne yadu amfani a cikin yadi masana'antu, inda shi hidima a matsayin wani muhimmin bangaren da tawada da kuma da dama daga ma'adinai Paints. Har ila yau, wannan abu ne mai kyau itace hana aifuwa na maza. Wasu da ake kira mafita na kashe-sarrafa baƙin ƙarfe sulfate a cikin irin insulating kayan matsayin ferron da ferrigips wakiltar cakuda hydrates wannan fili da daban-daban excipients.
