摘要

This paper presents the first use of ultrasound technique during electrochemical chloride extraction (ECE). The effect of ultrasound on the extraction efficiency was studied, and the mechanism of ultrasound in improving the extraction efficiency was also discussed in this paper. Testing results showed that ultrasound was conducive to enhance the efficiency of chloride removal to a certain extent, especially in the first 3 weeks. Ultimately, compared with ECE treatment, the chloride removal efficiency of ultrasonic-assisted ECE nearly increased 10%. In addition, the corrosion potentials measured 2 months after treatment indicated the effectiveness of ultrasonic-assisted ECE in protecting eroded rebars from further corrosion.
