The solubility iron mumvura. Ndinoita sei kuchenesa mvura kubva simbi?

Iron aripo mumvura iri muchimiro divalent uye trivalent ions. How kuchenesa mvura uye zvinwiwa kunwa kubva utachiona izvi? Dambudziko chairo kuti vanhuwo mhuri uye huru vachida. Funga zvikonzero pamusoro iyo simbi solubility mumvura, nokuumba dzinosvibisa kubviswa nzira ferrosoedineny.

Nei mvura kubva pombi riri yeyero uye shava?

Iron yeimwe mupe mvura ine yellowish ruvara, kazhinji risingafadzi kuravira, unogona kuona kusvibiswa muchimiro shava flakes. Izvi zviitiko - kuderera kwezvirongwa organoleptic zvivako mvura yokunwa. Color change - chii vatengi mvura raFungisisa pakutanga. Uyezve, pane migumisiro utano hwevanhu. Kwakakanganisa inokanganisa chiropa ezvinhu, meno nemudumbu, ganda uye bvudzi substandard kunwa mvura kubva pombi, sezvamakaropafadzwa simbi aripo.

Water solubility imhaka kwete chete kune kukurukurirana ferrosoedineny kubva pamatombo nevamwe zvinhu zvakasikwa. Anowedzera wevasungwa pamusoro Fe ²⁺ uye Fe ³⁺ ions nokuda ngura muitiro, riri ichi- ari apparatuses nenyere mvura yaigadzirwa nesimbi alloys. Mapaipi zvishoma nezvishoma kupinda yakapararawo, kushandura ehupfumi zvibereko, iyo yaishandiswa kugadzirwa mvura ine nokuputsanya yamatare.

Chii solubility resimbi mumvura?

Chemical chaikosha, uyo akapiwa Latin zita Ferrum, Inonyanya kubata goko paNyika riri munzvimbo yechipiri pashure aruminiyamu. Akawanda munyika pane deposits ose pyrite kana simbi pyrite (Fes ayo payakavakirwa _2). Ferrosoedineniya kuitika matombo kuputika uye sedimentary mavambo muchimiro hematite, magnetite, limonite.

A nyore fuma iron - munhu silvery grey ductile simbi iri insoluble mumvura. Oxides uye hydroxides, munyu vakawandisa simbi regai kushamwaridzana nemvura. Solubility mumvura kukurukura FeO nokuda kukwanisa rayo oxidize kune ferric oxide. Kana vanhu kutaura mvura FeO mhinduro, Zvichakadaro zviri ferrous ions. Vamwe matsime emvura, nhamba iyi inosvika 50 kana kupfuura milligrams muzana 1 fő. Izvi mukuru wevasungwa mvura yokunwa kwakadaro kunofanira acheneswe.

Iron opinda dzinongoitika mvura?

Mumuviri makemikari kukurwa kwevhu kunotungamirira kusabatana, nemukuparadzwa uye kuparadzwa mabwe ane simbi akakura. Somugumisiro siyana kuitika zvakasikwa vanosunungurwa ions Fe ²⁺ uye Fe ^3+. ivo vachishingaira mubasa redox kwendangariro. Divalent Ion iri oxidized, izvozvo donates ane Erekitironi uye anova trivalent. The solubility iron mumvura - ndiyo pamberi Fe ²⁺ cations. Somugumisiro richisvika maitiro mhinduro yaunganidzwa munyu siyana. Pakati pavo vane soluble Somuenzaniso sulfates uye insoluble (sulfides, carbonates). Deferrization Kana mvura yakadaro soluble chimiro iri kuchinjwa kuti insoluble, flakes vari yangoumbwa, chiito. Divalent simbi iri oxidised kuti trivalent pamberi okisijeni kana zvimwe oxidizing nevasori (ozone, kuiisa chlorine).

Transformations ions pakupedzisira kutungamirira kuti kwaita husingakwanisi mamwe oxidation dzebhurauni ngura, kwakajairika akafanana ayo anogona kupiwa chimiro ichi: Fe ₂ O ₃ • NH ₂ O. The PARTICIPLE unotora Fe ³⁺ vari kunzwisisa kuti inorganic uye Organic zvinhu izvo zvinowanika mvura .

Ita ferrosoedineny kugutsikana zvakafanana dzinongoitika mumvura?

The kuwanda makemikari chinhu uye simbi mumvura mhando kuvimba mhando Kuronga goko uye mamiriro zvinyorwa zvakasiyana. Panguva imwe chete inogona kuvapo vari divalent uye trivalent simbi yeimwe, makemikari siyana dzakadai simbi utachiona uye colloidal zvinhu (soluble uye insoluble).

Kana pane deposits pamusoro sulfate ores, zvingangoita kuti pamatunhu kuwanda achava aripo ferrous simbi. The solubility mumvura kunowedzera tembiricha ferrosoedineny pedyo kuputika nzvimbo. In Makungwa nenzizi yakakwirira kugutsikana esimbi, kana pane effluents metallurgia uye namakemikari zvinomera.

Ndinoita sei kuchenesa mvura kubva simbi?

Kubvisa ferrosoedineny akashandisa reagent uye reagentless nzira. Hwaro pezvakaitwa vakawanda ndiyo oxidation pamusoro ferrous Ion kuti trivalent nokuo- nga. Saizvozvowo zvinobva dzimwe tsvina mumvura - iri dzikwanise insoluble yeimwe uye vanobviswa pedyo firita. Pfungwa iyi inobva basa vakawanda maindasitiri zvivako.

Chii simbi solubility mumvura, takatsunga tichibatsirwa zviridzwa. Ipapo akatakura deferrization makemikari: okisijeni, kuiisa chlorine, ozone, potassium permanganate hydrogen peroxide. Kuitika makemikari maitiro ose oxidation, uye insoluble precipitate rwaiwanikwa. Haikwanise chete dzinobvisa asiwo kubvisa decantation pashure pakugadzirisa muitiro (batanidza pamwe yakaisvonaka mvura sludge). The ozonization uye chlorination mawa disinfection (disinfection). Zvinofungidzirwa kuti kushandiswa ozone - aizobudirira nzira nokuti kuiisa chlorine ngozi utano hwevanhu.

Ndedzipi nzira simbi kusukwa uwandu mvura duku?

Ari pamba ari pamusoro reactants inogona kushandiswa rehydrogen peroxide uye potassium permanganate. Ndinoita sei kuchenesa mvura kubva simbi, kana uchida kuwana zvishoma kwenguva pfupi? Kana kuwedzera peroxide mumvura sludge flakes kuwa. Zvakafanira kumirira kuti vakanyura makadzika pamusoro tangi uye kuti ubvise mvura, kana kuti zvakaitika nayo kuburikidza yenguva dzose chirongo firita. Izvi vakapfekenurwa mvura yakasvibiswa akakodzera nokunwa uye kubika.

Panyaya Organic siyana esimbi hadzibatsiri nzira dzakanyorwa. reagents avo vataurwa pamusoro apa, kutsanya zvakakwana kunokurumidziswa colloidal inoramba.

Ion rate uye catalysis - nzira rokubvisa simbi

Kune mon-woga yokugadza, uchishanda nenhungamiro catalysis, Ion exchange. Ivo inoshandiswa mvura yokunatsa mune diki maindasitiri mabhizimisi uye anamapako.

Iron ari CATALYTIC muitiro Via udalat backfill chaiyo kugadzirwa kubva dzinongoitika kana chakaita zvokugadzirwa feedstock. Filter nokuti Kubviswa simbi - chakaumbwa mugaba. Akaisa mukati zvinodiwa uye mvura akapfuura. The fuma iri anowedzera oxidation pamusoro divalent simbi, kushandura ndokuadira insoluble mamiriro zvakasiyana siyana.

Kana Ion Exchange rinoshandiswa deferrization nokuo- nga zvinobva Ion Exchange Inogadzirwa nemasiridzi anobuda mumiti, akadai zeolite (chicherwa). Mumakore achangopfuura, yakatanga kugadzirwa chakaita zvokugadzirwa zvigadzirwa kuti kubviswa simbi nokuda Ion exchange.

Nei Zvichidiwa ive nzira kuna reagents?

Clusive nguva makemikari anoshandiswa, kana pane ichi inokuvadza tsvina - simbi mumvura. Mhando dzamatare akasiyana, saka zvinokosha kuti anzvere Zvakanyanya Kunaka Panguva Yepamuviri mhinduro, nzira yakakodzera wokunatswa mvura chaiyo bhuku, uko vari hwavapo chimiro uye dare wevasungwa.

Chlorination chinhu chekare, ichi nenzira inokanganisa mvura yepamusoro uye voruzhinji utano. Aeration kana vapfume kwemvura mhepo - nzira substantially kuine zvainovhiringidzawo. Okisijeni iri vakayambuka mvura, simbi iri oxidized, uye insoluble precipitate flakes anogona kubviswa nokuda filtration kana sedimentation.

Kubviswa iron rinoitwa pasina mishonga - achiedza electrochemical nzira. The electrodes maviri achinyatsotaurira mugaba remvura kuti kudzimwa. The akaipa electrode - ari cathode - kukwezva uye anoramba chokwadi mhosva ions simbi, vagare vamwe chimiro. Chimwe Reagent isina nzira - kushandisa dzinokosha membranes.

Mumwe nemumwe Nzira idzi haana mikana chete, asi nekuipira. Pakusarudza nzira inoenderana chimiro umo simbi aripo mumvura.
