[Study on the coated carbon PVC membrane selective electrode of aconitine].
Coated carbon PVC membrane selective electrode of aconitine was prepared with the Aconitine-tetraphenylborate ion-associate complex as the electroactive material. The electrode showed a linear response to aconitine within the concentration range 1.0 x 10(-2) - 5.0 x 10(-5) mol/L. The limit of detection was 6.3 x 10(-6) mol/L and the slope of the electrode was 57.6 mV/decade. The authors established a basis and a method for the control of content limit of aconitine in Shen Fu Injection with this electrode.
