摘　　要：A simple,fast,precise and eco-friendly analytical method for the determination of uric acid（UA） in human urine by ion chromatography（IC） was established.The sample pretreatment was not required,only needed centrifugation and filtration.The separation was carried out on a cation exchange column with 2.0 mmol/L nitric acid as mobile phase at the flow-rate 1.0 mL/min.A non-suppressed conductivity detector was used.The IC analysis time for one run was within 10 min under the optimized IC condition.The detection limits were 0.5μg/L（S/N = 3） for uric acid.The recovery was 100.1%while the relative standard deviation （RSD） was 1.8%from 10 measurements.A simple,fast,precise and eco-friendly analytical method for the determination of uric acid（UA） in human urine by ion chromatography（IC） was established.The sample pretreatment was not required,only needed centrifugation and filtration.The separation was carried out on a cation exchange column with 2.0 mmol/L nitric acid as mobile phase at the flow-rate 1.0 mL/min.A non-suppressed conductivity detector was used.The IC analysis time for one run was within 10 min under the optimized IC condition.The detection limits were 0.5μg/L（S/N = 3） for uric acid.The recovery was 100.1%while the relative standard deviation （RSD） was 1.8%from 10 measurements.
