“…The testing instrument was fixed on the optical table (RL-2000 Series, Newport). The power supply system used to generate an electric field of any intensity is the same as Guo et al, 32 including a signal generator (DG2041A, Beijing RIGOL Technology Co., Ltd.), an oscilloscope (TDS2002B, Tektronix), and a high voltage source (Trek 20/ 20C, Trek company). A high-speed camera (Phantom v2512, Vision Research), a led lamp (LFP-60WF, OLYMPUS), and a five-way light quartz dish (12.5 × 12.5 × 40 mm, a wall thickness of 1.25 mm) were coaxially distributed.…”

Electromagnetic synergy is a more effective physical method than a single AC electric field (ACEF) to enhance oil–water separation. However, the electrocoalescence behavior of droplets dispersed with salt ions in oil under the synergistic electromagnetic field (EMSF) still lacks research. Herein, the evolution coefficient of liquid bridge diameter (C 1) characterizes the growth rate of the liquid bridge diameter, a series of Na2CO3-dispersed droplets with different ionic strengths were prepared, and C 1 values of droplets under ACEF and EMSF were compared. Micro high-speed experiments revealed that C 1 under ACEF is larger than C 1 under EMSF. In particular, when σ = 100 μS·cm–1and E = 629.73 kV·m–1, C 1 under the ACEF is 15% larger than C 1 under EMSF. Additionally, the theory of ion enrichment is put forward, which explains the influence of salt ions on ζ potential and total surface potential in EMSF. This study provides guidance for designing high-performance devices by introducing electromagnetic synergy in water-in-oil emulsion treatment.
