Abstract: Aquantitative equation of standard addition has been described as(1+Vs/Vx)×10Ape=(1+CsVs/CxVx) According to this equation, a diagram expressing the relationship between △pe and Vs has distinct advantages in comparison with Gran Plot and other reported methods, the former does not cause errors in the result treatment when non-standard slope electrodes are used.

Key words: Ion-selective electrode, Calculation diagram of standard addition
