▎ 摘　　要

NOVELTY - The method involves forming a loop by serially connecting a signal generator, a variable resistor, a fixed resistor and a conductivity cell. An oscilloscope is parallely arranged at ends of a fixed resistor and a conductive pool that is filled with 0.5-2 mg/ml of graphene oxide solution. Frequency and amplitude are set by the signal generator that is connected with the oscilloscope for adjusting the variable resistor. Stable oscilloscope signal voltage is recorded at ends of the fixed resistor and the conductivity cell that is formed with a rectangular glass groove. USE - Method for testing impedance characteristic of graphene oxide solution. ADVANTAGE - The method enables measuring impedance characteristic of graphene oxide solution in a simple, convenient and accurate manner at low cost. The method enables avoiding influence of a double layer on an electrode while testing and avoiding requirement of an additional instrument. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram illustrating a method for testing impedance characteristic of graphene oxide solution.
