A potentiometric method based on the usual titration of boric acid by means of invert sugar and NaOH, using a glass electrode and a saturated calomel reference electrode in an open container, was developed. Prior to the analysis, Fe, Hi, Cu, Cr, Mn, and other cations were separated by precipitation. Although the solution was brought to boiling for 5 min, no losses due to volatility were observed. In order to eliminate the aluminum that interferes with the determination, the solution was treated with citric acid. The presence of vanadium and molybdenum did not influence the results. The whole analysis could be completed within 1.5 hr. (TTT)
