摘要:

A rapid and sensitive detection method for the determination of 5-fluorouracil(5-FU) in real samples such as human urine and bovine serum albumin (BSA) was described. A carbon fiber microdisk electrode was used to perform end-column amperometric detection in capillary zone electrophoresis. The detection limit was as low as 2.5x10−7M and the wider linear range for the concentration was between 5x10−6and 1x10−4M with a correlation coefficient of 0.995.
