Monitoring the effluents of the trichloroacetic acid process by high-performance liquid chromatography

A simple and rapid high-performance liquid chromatographic method for the simultaneous determination of small amounts of nitric acid and trichloroacetic acid in process effluents was developed. Acidic components of the effluents were separated on a reversed-phase C 18 column using 0.15 M ammonium su...

Description
Summary:A simple and rapid high-performance liquid chromatographic method for the simultaneous determination of small amounts of nitric acid and trichloroacetic acid in process effluents was developed. Acidic components of the effluents were separated on a reversed-phase C 18 column using 0.15 M ammonium sulphate as mobile phase and determined quantitatively by UV absorption at 210 nm. The detection limits for nitric acid and trichloroacetic acid were 1.4 and 10 μg/l, respectively.
