ZIF-8@GO electrochemical sensor is fabricated via wrapping graphene oxide with ZIF-8 for the determination of Pb2+. The N2 adsorption data shows the pore size of ZIF-8@GO with 8.72 nm, which is larger than that of ZIF-8 and GO. The CV curve shows that the logarithm of the peak current value is linearly related to the logarithm of the scan rate, indicating that the reaction of Pb2+ on the electrode surface is controlled by both diffusion and adsorption process. Due to the synergy of ZIF-8 and GO, the modified electrode shows high selectivity toward Pb2+. And it has a low detection limit of 1.076 µM (S/N = 3) and a recovery between 90.6% and 100.3% in the actual sample detection, indicating that the sensor has good potential to detect Pb2+.
