hababka wax soo saarka ee birta xabagta huruud ah

Iron oxide yellow waa midab huruud huruud ah oo huruud ah. Cufnaanta qaraabada ayaa ahayd 3.5. Waxyaabaha kiimikada ahi way deggan yihiin. Cabbirka walxaha waa 0.01-0.02 μ M. Waxay leedahay aag gaar ah oo gaar ah (qiyaastii 10 jeer oo bir ah oksaydh caadi ah), nuugid ultraviolet xoog leh, iska caabin iftiin leh, iska caabbinta jawiga iyo waxyaabo kale oo wanaagsan Filimku waa mid hufan oo leh sifooyin wanaagsan. Sidee looga sameeyaa oksaydhka birta huruud ah?

 

Habka: Habka qiiqa birta ah ee loo yaqaan 'sulfate sulfate sulfate acid': sulfuric acid wuxuu la falgalaa fayl garaynta birta si loo sameeyo sulfate ferrous Sodium hydroxide waa lagu daraa oo hawo ayaa loo isticmaalaa in lagu oksiidey si loo diyaariyo nukleus crystal. Ferrous sulfate iyo birta birta ah ayaa lagu daraa ganaax ku-xidhka nukleus nucleus, kuleyl iyo hawo lagu afuufo qiiqa. Jaalaha Ferric oxide waxaa lagu diyaariyaa sifeynta cadaadiska, mayrinta, qalajinta iyo shiidi.

 

Fe + H2SO4 → FeSO4 + H2 ↑

Fe + H2SO4 → FeSO4 + H2 ↑

FeSO4 + 2NaOH → Fe (OH) 2 + Na2SO4

FeSO4 + 2NaOH → Fe (OH) 2 + Na2SO4

4Fe (OH) 2 + O2 → 4FeOOH + 2H2O

4Fe (OH) 2 + O2 → 4FeOOH + 2H2O

H2SO4 + Fe + 7H2O → FeSO4 · 7H2O + H2 ↑

H2SO4 + Fe + 7H2O → FeSO4 · 7H2O + H2 ↑

 

FeSO4 · 7H2O + O2 → 2Fe2O3 · H2O ↓ + 4H2SO4 + 2H2O

FeSO4 · 7H2O + O2 → 2fe2o3 · H2O ↓ + 4h2so4 + 2H2O xaaladaha falcelinta: ku dar 74g birta birta ah 1000ml 15% sulfuric acid ilaa ay birta birtu ka baaba'do, oo samee foornada milix leh oo ku urursan qiyaastii 200g / L. Ku filan 30% sodium sodium hydroxide waa lagu daray xalka milixdu kuleylka, iyo 40% wadarta birta ayaa loo rogayaa hydroxide ferrous [Fe (OH) 2] iyadoo si joogto ah loo walaaqayo, birtana waxaa lagu qalajiyay Fe si ay u sameyso nukleus crystal 30 ~ 35 ℃ Kadib 90 g / L feyl-ka ayaa lagu daray isku dar ah si loo sameeyo 7 g / L aaladda nukleerka iyo 40 g / L ferfeta sulfate, ka dibna la kululeeyo ilaa 85 ℃ qiiqa hawada xawaare ah 600 L / h 64 saac, iyo ka dib la sifeeyey, la maydhay, la qalajiyey oo la jajabiyey si loo helo huruud ferric oxide ah.
