Determination of oxalic acid in biological matrices by liquid chromatography with amperometric detection
Abstract:
Oxalic acid was separated from interfering compounds with a solvent-generated ion-exchange chromatographic system, and detected with a copper electrode amperometric detector. The lower limit of detection in standard solutions was 5 ng. Complex samples, such as vegetable extracts and urine, could be analysed with a minimum of sample preparation.
