Cov ntsiab lus ntawm magnesium oxide tau txiav txim los ntawm EDTA complexometric titration, triethanolamine ua tus neeg saib xyuas masking, chrome dub T raws li qhia thiab 0.02mol / LED TA raws li qhia ntawm pH 10. Cov ntsiab lus magnesia-calcium complexometric tau ntsuas ua ntej, ces cov ntsiab lus calcium tau rho tawm . Hauv Lavxias tus qauv, EDTA complexometric titration method siv. Hauv kev daws tom qab kev txiav txim siab calcium, magnesium hydroxide yog yaj los ntawm hydrochloric acid, thiab ammonia ntxiv rau kho kom pH tus nqi. Acidic chrome xiav dub yog siv raws li qhia, complexometric titration yog nqa nrog 0.1 mol / LED TA.
Lub teeb lub pob zeb magnesia tseem hu ua txoj kev sib tw iab thiab ua rau lub cev tsis muaj zog. Magnesium hydroxide (OH) 2, uas yog muab los ntawm tej lub pob zeb magnesite ore, brucite thiab seawater los yog brine, yog calcined ntawm 700-1000 C kom tau txais qhov muag uas muaj lub qhov muag kub nyhiab.
