I solubility yensimbi emanzini. Kungenzeka kanjani ukuthi ngibe ukuhlanza amanzi kusukela yensimbi?

Iron elikhona amanzi ngesimo divalent futhi trivalent ion. Indlela ukuhlanza amanzi nasoketshezini ophuza la ezingcolisa? Inkinga yangempela imikhaya abavamile futhi ibhizinisi elikhulu. Cabangela izizathu ku ngalo solubility yensimbi emanzini, yakha izindlela ukungcola ukususwa ferrosoedineny.

Kungani amanzi empompini ziphuzi futhi brown?

Iron compounds lwenze amanzi abe nombala aphuzi, ngokuvamile ukunambitheka ezingemnandi, ungabona ukungcola ngesimo ishq ensundu. Lesi senzakalo - Ukuwohloka izakhiwo organoleptic amanzi okuphuza. Umbala ushintsho - lokho abathengi pay amanzi ukunakwa kwasekuqaleni. Ngaphezu kwalokho, kukhona nemiphumela impilo yomuntu. Kubathinta kabi isimo isibindi, namazinyo emathunjini ipheshana, isikhumba nezinwele ukusetshenziswa eliphansi amanzi empompini, lapho insimbi likhona.

Amanzi solubility kungenxa nje kuphela ferrosoedineny nokuxhumana emadwaleni kanye nezinye izinto ngokwemvelo. Kukhulisa lokuhlushwa Fe ²⁺ futhi ion Fe ³⁺ ngenxa inqubo ukugqwala, okuyinto ngokuqhubekayo ku apparatuses futhi amapayipi amanzi aphenduke esuka yensimbi Alloys. Pipelines kancane kancane ingene labhidlika, ukushintsha izakhiwo umkhiqizo, esasetshenziswa esikhangisweni se ukukhiqizwa elinamanzi dash yensimbi.

Uyini solubility yensimbi emanzini?

Chemical isici, owanikezwa Igama Lesi'Latin Ferrum, ezivame kakhulu kuleli koqweqwe omhlaba endaweni yesibili ngemva aluminium. Inqwaba emhlabeni kukhona idiphozithi yanoma pyrite noma yensimbi pyrite (Fes ifomula ayo _2). Ferrosoedineniya zenzeka kwamadwala kwezintaba-mlilo futhi sedimentary ngesimo hematite, magnetite, limonite.

Into elula yensimbi - a silvery grey metal ductile okuyinto zingaxazululeki emanzini. Oxides futhi hydroxides, eziningi kakhulu yensimbi nosawoti musa uxhumana amanzi. Solubility emanzini ukuxoxa Feo ngenxa yekhono layo ukuze oxidize ukuze oxide ferric. Lapho abantu bakhuluma ngokuthuthukisa isixazululo amanzi Feo, okuqukethwe kusho ion ayoni. Eminye imithombo yamanzi, lesi sibalo ifinyelela 50 noma ngaphezulu angu ngamunye 1 ilitha. Lokhu emakamu eliphezulu kwamanzi ukuphuza kufanele bahlanzwe.

Iron singena emanzini zemvelo?

ukuguguleka Physical namakhemikhali kuholela kwehlukana, nokonakala nokubhujiswa rocks equkethe yensimbi kwakwakhe. Ngenxa yalokho ukusabela ezenzeka ngokwemvelo zikhishwa ion Fe ²⁺ futhi Fe ^3+. bona bahlanganyele izinqubo redox. Divalent ion oxidized, ke kaButhelezi i-electron futhi iba trivalent. I solubility yensimbi emanzini - kuba phambi cations Fe ^2+. Ngenxa yalokho ukufinyelela isixazululo ukuphendula etholwe nosawoti ahlukahlukene. Phakathi kwabo kukhona encibilikayo, isibonelo sulfate futhi zingaxazululeki (sulfides, carbonates). Deferrization Lapho amanzi ezifana ifomu encibilikayo is kuguquka i zingaxazululeki, ishq akhiwa, le ukugqashuka. yensimbi Divalent is oxidised ukuba trivalent ebukhoneni-mpilo noma ezinye oxidizing ejenti (i-ozone, chlorine).

Kugucuka ion luholele ukuvela amelana namachibi obengeziwe nokugqwala ensundu, ngezithako zawo ezivamile kungenziwa eyethulwe kuleli fomu: Fe ₂ O ₃ • NH ₂ O. I kuyizinhlayiyana yakhiwa Fe ³⁺ ku eyinkimbinkimbi izinto wezinto ezingaphili futhi organic ezitholakala kwamanzi .

Ingabe okuqukethwe ferrosoedineny ngokulinganayo emanzini zemvelo?

I lokuhlala element zamakhemikhali yensimbi e izinhlobo amanzi kuxhomeke Ukwakheka zama-kuqweqwe isimo emithonjeni ehlukene. Kanyekanye kungenzeka abakhona divalent futhi trivalent yensimbi compounds, amafomu organic ezifana amagciwane yensimbi kanye izinto colloidal (encibilikayo futhi zingaxazululeki).

Uma kukhona idiphozithi yanoma imikhando sulfate, cishe ukuthi lokuhlala eliphezulu uzoba khona yensimbi ayoni. I solubility emanzini kwandisa ne lokushisa ferrosoedineny eduze izindawo mlilo. Emachibini noma emifuleni ephakeme okuqukethwe yensimbi, uma kukhona effluents izitshalo Metallurgical namakhemikhali.

Kungenzeka kanjani ukuthi ngibe ukuhlanza amanzi kusukela yensimbi?

Ukuze ususe ferrosoedineny esetshenziswa reagent nezindlela reagentless. Ngesisekelo izinqubo kakhulu namachibi ion ayoni kuya seka trivalent. Ngokufanayo abavela kwamanye ukungcola emanzini - is iguqulwe ibe izakhi zingaxazululeki futhi ziyasuswa okokuhlunga. Lomgomo kusekelwe umsebenzi ukufaka kakhulu ezimbonini.

Yini yensimbi solubility emanzini, kunqunywa ngosizo amathuluzi. Khona-ke okwenziwa deferrization amakhemikhali: i-oksijini, chlorine, ozone, potassium permanganate, i-hydrogen peroxide. Wenzeka yokusabela chemical of namachibi, kanye kwenze zingaxazululeki etholwe. Ngeke nje kuphela ukuhlunga, kodwa futhi ukususa decantation emva inqubo (uhlangane ne okumsulwa amanzi kodaka) sokuxazulula. I ozonization futhi chlorination magciwane kanyekanye (magciwane). Kukholakala ukuthi ukusetshenziswa-ozone - indlela ethembisa ngoba chlorine kuyingozi kwempilo yabantu.

Yiziphi izindlela yensimbi ukususwa nengcosana amanzi?

In imvelo ekhaya we reactants ngenhla ingasetshenziswa i-hydrogen peroxide kanye potassium permanganate. Kungenzeka kanjani ukuthi ngibe ukuhlanza amanzi kusukela yensimbi, uma ufuna ukuthola inani elincane isikhathi esifushane? Uma wengeza peroxide emanzini kodaka ishq iwe. Kuyadingeka ukuba ulinde ukuthi waguqa phansi ethangini sokukhipha amanzi, noma balidlulisele ngokusebenzisa evamile imbiza zokuhlunga. Lokhu abaphundlwe amanzi angcolile efanelekayo ukuphuza nokupheka.

Mayelana amafomu organic zensimbi izindlela ayizwakali efakwe ohlwini. Labo reagents okukhulunywe ngaye ngenhla, fast ngokwanele ukugqashuka izinhlayiya colloidal.

Ion exchange futhi catalysis - izindlela yensimbi ukususwa

Kukhona ukufakwa azimele wodwa, ezisebenza kumigomo catalysis, ion exchange. Zisetshenziswa ngoba umshini ohlanza amanzi e amabhizinisi amancane zezimboni kanye Cottages.

Iron enqubeni okhanda amanye amathuba nge udalat backfill ekhethekile ekhiqizwa kusuka feedstock zemvelo noma zokwenziwa. Hlunga sensimbi ukususwa - esitsheni metal. Lapho esebekwe ukuba abe ngaphakathi ukugcwaliswa futhi amanzi sidlulile. Ingqikithi kuyinto kulethe namachibi yensimbi divalent, ilihumusha ku isimo lwezinhlobo ezahlukene zingaxazululeki.

Lapho ion exchange isetshenziswa deferrization seka ethathwe ion exchange inhlaka, ezifana zeolite (amaminerali). Eminyakeni yamuva, umkhankaso ukukhiqizwa imikhiqizo engama synthetic sensimbi yokususa ion exchange.

Kungani Kudingeka Imithombo elinye ithuba reagents?

asetshenziswa Clusive isikhathi amakhemikhali, uma kukhona lokhu eziyingozi ukungcola - yensimbi emanzini. Amafomu yensimbi zihlukile, ngakho-ke kuyadingeka ukuba afune ikhambi elilungile, indlela efanelekayo ukuhlanzwa amanzi emthonjeni ethize, elingenabo zixhunywe ifomu kanye lokuhlushwa yensimbi.

Chlorination into yesikhathi esidlule, ngale ndlela nomthelela ongemuhle izinga lamanzi kanye nempilo yomphakathi. Aeration noma kwandzisa amanzi nge air - indlela kakhulu elingenalo kahle. Mpilo badabula amanzi, insimbi oxidized, kanye zingaxazululeki kwenze ishq kungenziwa isuswe ngu filtration noma sedimentation.

Ukususwa yensimbi Kwenziwa ngaphandle amakhemikhali - usebenzisa indlela electrochemical. I electrode amabili afakwa esitsheni yamanzi lisuswe. I electrode negative - the cathode - edonsela futhi azigcina kahle icala athomu okusansimbi, bangase babe ngandlela thile. Enye indlela Reagent-free - ukusetshenziswa ulwelwesi ekhethekile.

Ngayinye yalezi zindlela kunezinzuzo hhayi kuphela, kodwa nobubi obuthile. Kukhethwa indlela incike kundlela odinga ngayo lelo insimbi asemanzini.
