【Abstract】 Triangular-wave current sweeping was used in AC oscillopolarography instead of sine-wave current. The oscillopolarogram obtained is similar to that obtained with sine-wave current. The appearance or disappearance of incision on the oscillopolarogram can be used to indicate the end-point of titration. The relationship of incision height hi to the concentration of depolarizer and current sweeping rate V are respectively as follows.hi(mV) = -0.02300 + 4.702×10-4C0*(-2/3) hi(mV)= -0.02807 +950.68V(2/3)When V is very lower 5.0×10-9mol/L Tl+ ion can be determined by this method更多还原
