Txoj kev npaj ntawmpoov tshuaj bromide hmoov:

Cov poov tshuaj bromide synthesized los ntawm bromine thiab poov tshuaj hydroxide yog yaj nyob rau hauv dej distilled los npaj electrolyte. Tom qab electrolysis rau 24h, thawj batch ntawm crude khoom yog tsim. Tom qab ntawd, cov khoom siv raw yog noj txhua txhua 12 teev. Tom qab cov poov tshuaj bromide raug tshem tawm los ntawm kev ntxuav dej, cov khoom nyoos yog distilled thiab hydrolyzed. Ib qho me me ntawm cov poov tshuaj hydroxide yog ntxiv los kho tus nqi pH mus rau 8. Tom qab kev txuag hluav taws xob rau 0.5h, cov lim tau lim. Lub clarified filtrate yog txias rau chav tsev kub hauv lub crystallizer. Tom qab crystallization, sib cais, ziab, cov khoom siv poov tshuaj bromate yog npaj.

Tom qab cov kua txiv qaub reacts nrog bromine, cov roj chlorine tau qhia rau cov tshuaj chlorine oxidation, thiab cov tshuaj tiv thaiv raug txiav tawm thaum tus nqi pH nce mus txog 6 ~ 7. Tom qab tshem tawm slag, evaporate lub filtrate.
