摘　　要：A new and simple method was developed to determine anions in oxalate of analytical reagent grade. After UV photolysis with optimal 1% H2O2 in 10,000 mg/L oxalate in the fabricated photoreactor, sample was directly injected into IC system. Satisfactory linearity, detections limits, good repeatability and spiked recovery were obtained. The method was successfully applied to determine anions in two commercial oxalate samples.A new and simple method was developed to determine anions in oxalate of analytical reagent grade.
