BUFFER FOR BOD CAS 10049-21-5 yog dab tsi?

Sodium Phosphate Monobasic Monohydrate yog tsim los ntawm phosphoric acid ua raw khoom, ntxiv nrog dej txaus, rhuab mus rau 80-90 ℃, stirred tusyees, thiab ces txias rau chav tsev kub. Hauv lwm lub tank tshuaj tiv thaiv, ntxiv qhov tsim nyog ntawm sodium hydroxide rau dej rau kev sib cais. Maj mam tso cov tshuaj sodium hydroxide uas tau txais nyob rau hauv lub kauj ruam thib ob rau hauv cov tshuaj phosphoric acid nyob rau hauv cov kauj ruam, thaum stirring tas li kom txog rau thaum ob yog kiag li reacted thiab ib tug dawb precipitate yog tsim. Lim kom tau txais precipitate, ntxuav nrog dej deionized, thiab tom qab ntawd qhuav ntawm qhov kub thiab txias kom tau txais sodium dihydrogen phosphate monohydrate.
