Yuav Ua Li Cas Kuaj Sodium Sulphate kom paub txog qhov huv thiab zoo?
Sodium sulfate (Qhov ntawd2Yog li ntawd4 ) yog ib qho tshuaj inorganic tseem ceeb hauv kev lag luam uas siv dav hauv cov tshuaj ntxuav tes, kev tsim iav, kev zas xim ntaub, kev ua cov ntawv pulping, thiab kev tsim tshuaj lom neeg. Vim tias cov khoom tsis huv me me—xws li cov hlau hnyav, hlau, chlorides, lossis dej noo—tuaj yeem hloov pauv kev ua haujlwm ntawm cov khoom hauv cov txheej txheem kev lag luam no, kev tswj xyuas zoo thiab kev kuaj hauv chaw kuaj mob yog qhov tseem ceeb ua ntej xa tawm.
Txawm hais tias lees paub qhov tseeb ntawm anhydrous sodium sulphate lossis hydrated variants (Glauber's salt), cov chaw tsim tshuaj lom neeg thiab cov kws ua haujlwm tswj xyuas zoo vam khom cov txheej txheem kuaj xyuas tus qauv los xyuas kom meej tias cov tshuaj lom neeg huv thiab qib ua raws li qib. Nov yog kev saib xyuas ntxaws ntxaws ntawm cov txheej txheem tshuaj ntsuam xyuas tseem ceeb siv los kuaj sodium sulphate, nthuav tawm los ntawm CNCchemist.
1. Kev Ntsuas Kev Ntsuas (Feem Pua ntawm Kev Huv)
Qhov kev sim tseem ceeb rau qhov zoo ntawm sodium sulphate yog txiav txim siab nws cov ntsiab lus feem pua (feem ntau xav tau ≧ 99.0% kev huv rau cov qib kev lag luam thiab tshuaj lom neeg).
Txoj Kev Ntsuas Barium Sulfate:Tus qauv kub rau kev ntsuas qhov ntau ntawm cov ntsuas suav nrog kev ntsuas qhov hnyav ntawm cov nag lossis daus. Ib qho qauv sodium sulphate uas hnyav lawm raug yaj rau hauv dej distilled thiab acidified nrog hydrochloric acid. Barium chloride (BaCl2) cov tshuaj ntxiv rau cov sulphate ions uas ua rau barium sulphate (BaSO4) poob qis.4). Cov av noo raug lim, ntxuav, hlawv rau hauv lub cub tawg ntawm qhov kub siab, thiab hnyav.
Kev Titration ntawm Ion Exchange:Rau kev kuaj mob sai, cov tshuaj sodium sulphate raug dhau los ntawm cov kab cation-exchange resin uas muaj zog heev. Cov hydrogen ions uas tau yaj tawm (H+) ces raug titrated tawm tsam cov kua sodium hydroxide (NaOH) volumetric siv phenolphthalein ua tus qhia.
2. Kev Ntsuas Cov Khoom Uas Tsis Muaj Peev Xwm
A. Cov Hlau (Fe) Cov Ntsiab Lus
Kev ua qias tuaj ntawm hlau tuaj yeem ua rau muaj kev hloov pauv loj heev hauv cov tshuaj ntxuav tes, iav, thiab ntaub. Kev kuaj xyuas suav nrog kev yaj cov qauv thiab ua rau nws cuam tshuam nrog ammonium thiocyanate lossis 1,10-phenanthroline los ua ib qho xim sib xyaw. Tom qab ntawd ntsuas qhov absorbance siv spectrophotometry tawm tsam cov tshuaj hlau paub kom ntseeg tau tias cov ntsiab lus tseem nyob hauv qab qhov txwv nruj (feem ntau
B. Cov Hlau Hnyav (raws li Pb)
Kev ntsuas qhov muaj kuab lom ntawm cov hlau hnyav yog siv cov kev ntsuas xim. Cov kua qauv raug kho kom haum rau cov pH tshwj xeeb thiab ua rau muaj kev cuam tshuam nrog hydrogen sulfide lossis sodium sulfide reagent. Qhov tsaus ntuj ntawm cov xim uas tshwm sim yog piv rau cov kua txhuas (Pb) tus qauv.
C. Chloride ($\text{Cl}^-$) thiab Calcium/Magnesium Ions
- Kev Ntsuas Chloride:Soj ntsuam los ntawm kev siv nephelometry lossis argentometric titration siv silver nitrate (AgNO3)3) cov tshuaj reagent los tsim cov nyiaj chloride opalescence.
- Calcium thiab Magnesium:Ntsuas los ntawm kev titration complexometric EDTA siv Eriochrome Black T lossis murexide indicators los tiv thaiv kev nce qib tsis xav tau hauv cov dej ntws.
3. Kev Tshuaj Xyuas Cov Qauv Lub Cev thiab Cov Tshuaj Lom Zem
| Kev Ntsuas Kev Ntsuas | Txoj Kev Ntsuas | Kev Lag Luam Tseem Ceeb |
| Poob Thaum Qhuav (Ntsuab) | Sov hauv qhov cub ntawm 105 ℃ - 110 ℃ kom qhov hnyav tas li | Ua kom ntseeg tau tias qib anhydrous muaj kev ncaj ncees thiab tiv thaiv kev sib sau ua ke thaum lub sijhawm khaws cia |
| pH ntawm Cov Tshuaj Aqueous | Kev ntsuas potentiometric ntawm 5% lossis 10% cov kua | Pom tseeb tias tus cwj pwm tshuaj lom neeg tsis muaj teeb meem (pH6.0 - 8.0) |
| Cov Khoom Uas Tsis Yaj Hauv Dej | Kev lim dej los ntawm lub crucible calibrated tared | Tiv thaiv kom lub qhov nozzle tsis txhob txhaws hauv cov da dej xim textile thiab cov kua dej |
| Kev dawb thiab tsos | Reflectance colorimeter / kev tshuaj xyuas pom | Tseem ceeb rau cov tshuaj ntxuav hluavtaws zoo thiab kev tsim ntawv |
4. Cov Txuj Ci Siv Niaj Hnub
Hauv kev sim tshuaj lom neeg uas muaj zog heev, kev ntsuas gravimetric thiab kev ntsuas tshuaj ntub dej tau ntxiv los ntawm cov cuab yeej siv hauv chav kuaj mob siab heev:
- Kev Ntsuas Plasma Optical Emission Spectrometry (ICP-OES):Muab kev tshawb nrhiav cov hlau hnyav, hlau, calcium, thiab magnesium tib lub sijhawm mus txog rau qhov txwv ntawm qhov ntsuas ib billion (ppb).
- Kev Siv Ion Chromatography (IC):Muab kev ntsuas qhov tseeb thiab tsis siv neeg ntawm cov sulphate anions nrog rau cov kab mob me me xws li nitrate lossis chloride.
