Abstract Dissolution characteristic of Cu in BMIMBF4 ionic liquid under different oxygen partial pressures and temperatures was investigated, and the saturation concentrations of Cu2+ in BMIMBF4 were also measured. The experimental results showed that Cu can only be dissolved in BMIMBF4 in the presence of oxygen and the dissolution rate of Cu2+ in BMIMBF4 improved with increase in the oxygen partial pressure and temperature. In addition, according to the experimental data, The value of apparent activation energy was found to be \linebreak21.76 kJ/mol in the temperature range from 25℃ to 70℃ under the oxygen partial pressure of 2.10×104 Pa. The dissolution rate equation of Cu in BMIMBF4 was obtained.
