摘要

用硫化钠作沉淀剂,从含铑强酸性水溶液中沉淀富集铑金属。通过实验确定了影响铑沉淀率的诸多因素,如沉淀剂加入量、沉淀温度、沉淀剂硫化钠加料速度、陈化时间及搅拌速度等。结果表明,当沉淀剂硫化钠与铑的物质的量比为10、沉淀温度为100 ℃、硫化钠加入速度为5 mL/min、陈化时间为1 h、搅拌速度为600 r/min时,铑沉淀率达到最大,铑沉淀率最高为99%以上。富集后溶液铑含量低于1 mg/kg,铑富集效果明显。

Abstract

Sodium sulfide was used as precipitant to precipitate and enrich rhodium metal from rhodium containing strong acid aqueous solution.Many factors affecting the rhodium precipitation yield were determined through experiments,such as the amount of precipitant,precipitation temperature,feeding speed of the precipitant of sodium sulfide,aging time and stirring speed.The results showed that when amount-of-substance of the precipitant of sodium sulfide and rhodium was 10,precipitation temperature was 100 ℃,adding speed of sodium sulfide was 5 mL/min,aging time was 1 h and stirring speed was 600 r/min,the yield of rhodium precipitation reached the maximum.The highest yield of rhodium precipitation was more than 99%.After enrichment,the rhodium content in the solution was less than 1 mg/kg and the effect of rhodium enrichment was obvious.
