The determination of sulfuric acid in technical pure lactic acid
Komenský University, Bratislava
Abstract: A rapid indirect polarographic method is described for the detn. of H2SO4 in tech. pure lactic acid. In place of alc., acetone was used to decrease the soly. of sulfates, so that they are sepd. quantitatively as a cryst. easily filterable ppt. The max. error was 1.2-0.4 mg./100 ml. It is mostly dependent on the amt. of pipeted filtrate after the sepn. of sulfates.
