Abstract
The organic boron in sodium thriacetory borohydride was converted into borate through dry cinefaction.Then borate was converted into boric acid on condition of suitable PH.At last,the acidity of the boric acid was enhanced with mannite,the content of the boric acid was determined through acid-base titrimetric and the content of the sodium thriacetory borohydride was computed.Precision and accuracy of this method is good.Standard deviation is 0.39%.Relative standard deviation is 0.39%.Percent recovery is 100.10%.
