中文摘要:
      铑的高效快速溶解是其冶金领域的关键环节,并且是公认的技术难题。研究了电化学溶解铑的工艺,探索了液固比、电极直径大小、反应液中铑浓度对铑粉溶解速率的影响。结果表明,合理的液固比为15~90 mL/g;电极直径越大铑粉溶解速度越快;铑浓度过高抑制铑粉的溶解。在最佳反应条件下铑粉溶解速率为1 g/h。
英文摘要:
      The high efficient and quick dissolution of rhodium is a key part and a recognized technical problem in the field of rhodium metallurgy. The process of dissolving rhodium by electrochemical method was studied. Effects of factors, such as the liquid-solid ratio, the diameter of the electrode and the concentration of rhodium in solution on rhodium dissolution rate were investigated. The experimental results show that, the ratio of liquid-solid ratio is reasonable between 15~90 mL/g, the dissolution rate of rhodium powders is positive correlated with the electrode diameter and is negative correlated with the rhodium concentration. Under the optimum reaction conditions, the dissolution rate is 1 g/h
