    Ion Imprinted polymer (IIP) is a traditional material for selective removal of ions, but its low adsorption capacity and high cost limit widely practical application. Exploring a novel material with high adsorption capacity and low cost to capture Pb2+ is necessary but very challenging. Herein, a novel Pb2+ imprinted Janus magnetic micromotor was successfully fabricated by hydrothermal, impregnation calcination, photoreduction and ion imprinted method using naturally available and low-cost lotus pollen as biological template. The results show that the asymmetric spherical micromotor was able to have a highly selective adsorption ability to Pb2+ in sewage and the maximum adsorption value reaches 67.12 mg/g. The adsorption process of the kinetics and thermodynamics of Pb2+ follow well in line with pseudo-second-order kinetic model and Langmuir isotherm model. In addition, the prepared samples not only have good magnetism for direction control and recycling, but also exhibite excellent reusability in practical application. This work provides an effective strategy for effcient and selective removal of Pb2+ from sewage.
