field, the mass transfer of Cu2+ toward electrode surface can be promoted. The concentration polarization of Cu2+ becomes small and current efficiency increases. Meanwhile, the huge gravity acceleration..., but the value was up to 56.8% under G value of 25. Fig.3 Effect of super gravity field on current efficiency in lower concentration of CuSO4 (Electrolyte: 5 g/L CuSO4+9.8 g/L H2SO4+1.5 g/L SDS) According......
