Tam sim no, tsis muaj cov khoom siv reagent txhim khu kev qha rau kev ntsuas qhov purity ntawm magnesium oxide uas tuaj yeem siv tau yooj yim ntawm - qhov chaw sim. Kev txiav txim siab tseeb ntawm magnesium oxide purity yuav tsum muaj tshuaj ntsuam xyuas hauv chav kuaj, xws li acid-base titration, hydration txoj kev txiav txim siab active magnesium oxide, thiab ion chromatography rau kuaj impurities. Cov txheej txheem no tsis tuaj yeem ua tiav nrog cov khoom siv reagent.
Vim li cas thiaj tsis muaj cov khoom siv reagent tsim nyog?
Cov Khoom Ntsuas Cov Khoom: Magnesium oxide purity yuav tsum tau txiav txim siab ntawm ntau qhov ntsuas, suav nrog MgO cov ntsiab lus, nquag magnesium oxide, Cl⁻, SO₄²⁻, Fe₂O₃, thiab CaO, suav nrog cov tshuaj sib txawv thiab cov cuab yeej ntse, ua rau nws nyuaj rau kev sib xyaw ua ke rau hauv ib qho khoom siv.
Cov Kev Xav Tau Kev Ruaj Ntseg Siab: Cov kev txwv impurity tsawg kawg nkaus (xws li, Cl⁻ Tsawg dua lossis sib npaug li 0.02%), xav tau ppm- qib kev muaj peev xwm nrhiav tau. Cov txheej txheem colorimetric lossis cov ntawv xeem tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua.
Cov xwm txheej nruj heev: Piv txwv li, "txoj kev hydration rau kev txiav txim siab active magnesium oxide" yuav tsum muaj qhov kub thiab txias ntawm cov tshuaj tiv thaiv lub sij hawm ntau tshaj 2 teev thiab muaj cov kev cai nruj rau cov dej zoo thiab cov ntim huv si, ua rau nws tsis haum rau ntawm - chaw ua haujlwm.
Feem ntau cov khoom lag luam muaj "cov khoom siv kuaj nrawm" yog cov khoom siv zoo lossis ib nrab- cov khoom lag luam uas muaj qhov yuam kev loj thiab tsis tuaj yeem siv los ua lub hauv paus rau kev tso tawm kom zoo.
