中文摘要: 以报废汽车高值元器件废催化剂为原料,探讨了铂、钯、铑的浸出条件。分别研究了氧化浸出过程中盐酸浓度、时间、温度、氯酸钾百分比、固液比等对铂、铑、钯浸出率的影响。结果表明,较佳浸出工艺条件为:盐酸浓度9 mol/L、反应时间2 h、反应温度90 ℃、氯酸钾百分比5%、固液比0.20 g/mL、搅拌速率400 r/min,在上述工艺条件下,铂、钯、铑的浸出率分别为95.15%、96.44%、83.30%。
Abstract:Leaching conditions of Pt, Pd and Rh from spent automobile catalyst of high value components of end-of-life vehicle were discussed. Effects of hydrochloric acid concentration, leaching time, leaching temperature, potassium chlorate percentage, and ratio of solid to liquid on leaching rate of Pt, Pd and Rh during acid leaching process of spent automobile catalyst were studied. The results show that leaching rate of Pt, Pd and Rh is 95.15%, 96.44% and 83.30%, respectively, under the optimum leaching conditions including concentration of hydrochloric acid of 9 mol/L, reaction time of 2 h, reaction temperature of 90 ℃,potassium chlorate dosage of 5%, ratio of solid to liquid is 0.20 g/mL, and stirring speed of 400 r/min.
