摘要：

A simple, rapid and accurate ion-exclusion chromatographic method coupled with a UV detector for the determination of uric acid in human urine samples has been developed. The separation was carried out on an ion-exclusion column using only pure water as mobile phase. The detection wavelength was 254 nm and urine sample was injected directly without any pretreatment. Furthermore, the retention behavior of uric acid on the ion-exclusion column was researched when pure water and 1 mmol.L-1 HCl were used as mobile phase, respectively. The stability of uric acid was also further investigated within 28 days. In this method, the linear range of the calibration curve for uric acid was 0.25100 mg.L-1, and the detection limit calculated at S/N=3 was 0.02 mg.L-1. The proposed ion-exclusion chromatographic method has been used for the determination of uric acid in human urine.
