摘要:
通过电解小试实验,研究甲酸、乙酸、柠檬酸、酒石酸、乌头酸、葡萄糖及蔗糖等有机物对锰电解电流效率(MECE)的影响.结果表明:甲酸、乙酸和柠檬酸等有机酸在一定质量分数范围内均可提高锰电解电流效率,达73%左右,最高可达77.9%,但有机酸质量分数过高,锰电解电流效率反而降低;葡萄糖和蔗糖粘度较高、质量分数过大,会阻碍电解液中离子的迁移,从而导致锰电解电流效率下降.
Abstract:
The effects of organics such as formic acid, acetic acid, citric acid, tartaric acid, aconitic acid, glucose and sucrose on the manganese electrolysis current efficiency(MECE)were studied. The results show that within a certain range of concentration, organic acids such as formic acid, acetic acid and citric acid can improve the MECE to about 73%, and the highest MECE reaches 77.9%. However, when the concentration is too high, the MECE decreases. Moreover, the high viscosity and large mass fraction of glucose and sucrose hinder the ion transportation, which consequently leads to the reduction of current efficiency.
