Routine Micromethod for Determination of Oxalic Acid in Urine by Atomic Absorption Spectrophotometry

R. Menachè 1

1 Laboratories of Clinical Chemistry, Hasharon Hospital, PetahTikva, Israel.

The method of Gitelson et al. was modified to a microscale procedure and adapted for atomic absorption spectrophotometry. Oxalic acid in urine is precipitated with excess of calcium ions at pH 5. The excess of calcium present in the supernate and the total calcium added and present in the urine at pH 2 are determined by atomic absorption spectrophotometry. The oxalic acid present in the precipitate is calculated indirectly from the difference between the two determinations of calcium. This method is useful for routine determination of urinary oxalic acid.
