抄録

A selective and sensitive method for the determination of oxalic acid using the electrogenerated chemiluminescence (CL) system, oxalate-Ru(bpy)₃²⁺, was described. Oxalate was reacted with Ru(bpy)₃³⁺ continuously prepared from Ru(bpy)₃³⁺ with an electrochemical reactor (ECR, home-made). The dual channel FIA apparatus was comprised of a delivery pump for both carrier and reagent solutions, a sample injector, damper tubing, the ECR and a photon counter. The oxidation potential of the working electrode in the ECR was maintained with a potentio-galvanostat. CL intensity was measured with a photon-counter which recorded FIA peaks graphically. The carrier solvent was H₂O (flow rate, 0.3 ml/min^-1) and reagent solution prepared in 10 mM H₂SO₄ to contain 0.12 mM Ru(bpy)₃Cl₂ (flow rate, 0.8 ml min^-1). The sample (10 μl) was injected into the carrier stream. Linearity was obtained up to 16 pmol for oxalate. The detection limit was 0.3 pmol (S/N=3). The relative standard deviation was 2.3% (n=5, 5 pmol). This method was successfully applied to the determination of oxalate in urine.
