Abstract
The present invention discloses a detection method for low-concentration metal ions in solution, which avoids damage of strong acids and strong alkalis to the field effect transistors (FET) while using a control solution as a reference for calibration. By adjusting the electronic signals (resistance, inductance, current, voltage, etc.) generated by the solution to be tested and the control solution to be the same, the voltage difference therebetween is employed to quantitively infer the metal ions concentration of the solution to be tested.
