摘要: 在不同氧分压和温度下，研究Cu片在BMIMBF₄离子液体中的溶解速率，并测定Cu²⁺在BMIMBF₄离子液体中的饱和浓度。结果表明，Cu必须有氧存在才能溶解在BMIMBF₄离子液体中，且溶解速率随氧分压和温度的增加而加快。根据实验数据得到在25℃~70℃和2.10×10⁴ Pa 的氧分压下，Cu溶解速率的表观活化能为21.76 kJ/mol，并建立Cu在 BMIMBF₄离子液体中溶解的速率方程。

关键词 ： Cu, 溶解, BMIMBF₄离子液体, 氧分压

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 BMIMBF₄were 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.

Key words： Cu dissolution BMIMBF₄ ionic liquid oxygen partial pressure
