Abstract: The optimization of electroosmotic efficiency by improving interface resistance has received widespread attention. Based on the researches on magneto electrochemistry, a magnetic field is innovatively introduced into the electroosmotic process, aiming to reduce interface resistance and improve electroosmotic efficiency. Through experiments, it is demonstrated that introducing a magnetic field can significantly improve the efficiency of electroosmosis, and the optimal placement is at the anode. Specifically, a reasonable arrangement of magnetic fields can significantly delay the increase in anode interface resistance, improve the electro osmotic drainage performance, and significantly shorten the processing time. In terms of energy consumption, multiple indices are employed for comprehensive analysis, including equivalent energy consumption, total energy consumption and energy utilization rate. The results show that introducing a magnetic field is an effective way to solve the problem of high energy consumption in electroosmosis, especially when the magnetic field is arranged at the anode, and it can significantly improve energy utilization rate and reduce total energy consumption. Among them, the reusable permanent magnets are used as magnetic poles, which can be reused and have low cost. Therefore, objectively speaking, the technology of introducing magnetic fields in electroosmosis has great engineering application potential and practical value.
