| 摘 要： | 采用水溶液氯化法、王水溶解法和水溶液氯酸钠氧化法等3种湿法工艺从含铑树脂中回收铑，重点研究了溶解体系、反应温度、反应时间和液固比等对铑溶解率的影响。结果表明，在液固比12:1 mL/g、反应温度90℃、反应时间20 h的条件下，采用水溶液氯化法铑溶解率达到95%，经精炼后得到合格铑粉，铑的回收率达到92%。

| Abstract: | Three wet processes, including the aqueous chlorination and aqua regia dissolution and oxidative dissolution with sodium chlorate, were used and compared in recovering rhodium from the rhodium-containing resin, and the influence of the reaction temperature, reaction time and liquid-solid ratio on the dissolution rate of rhodium was investigated. The results showed that a dissolution rate of 95% could be accomplished by adopting the aqueous chlorination process at a reaction temperature of 90°C for 20 h with a liquid(in mL)-solid(in gram) ratio of 12:1. After refining, rhodium powder in line with quality standards was obtained with a recovery rate of 92%. |
