摘　　要：用石墨粉66.7%、液体石腊20.0%和13.3%甘油制备了头孢噻肟伏安传感器。在0.030mol/LH_3PO_4-0.00060mol/L KNO_3-0.0020% Triton X-100溶液中,CFTM在-0.97V处产生—灵敏阴极溶出伏安峰。在-0.50V富集90s,检测下限为5.0×10^(-9)mol/L。Cefotaxime vohammetric sensors containing 66. 7% graphite powder, 20. 0% liquid paraffin and 13. 3% glycerol was prepared. In a 0. 030mol/L H3PO4 solution containing 0. 00060mol/L KNO3 and 0. 0020% Triton X-100, cefotaxime yields a sensitive cathodic stripping vohammetric peak at -0. 97V. The peak current was responded to the concentration of cefotaxime in the range 5. 0×10-9-2.0×10-7mol/L, the detection limit was 2.0×10-9 mol/L.
