【Abstract】 ?Ketoglutaric acid is determined by use of the Nafion-mercury film chemically modified electrode (Nafion-Hg film CME). The activity of GPT in human serum is determined indirectly. The linear range for the determination of α-ketoglutaric acid is 5. 0×10-3 1. 0×10-6 mol.L. The lowest detection is 5.0×10-7mol/L.The range for the determinaion of GPT is 2-200 U/L. This method has a high sensitivity and resists with disturbance.Good results were obtained for tests of human blood samples.更多还原
