Abstract: The ultrasonic oxidation digestion method was used for the separation and recovery of rhenium from the rhenium-containing ionic liquids, using 35% of hydrogen peroxide solution and acetic acid as the oxidizing agent. When the concentration of the perrhenate based ionic liquid is 2.5 mmol, 35% the H2O2 aqueous solution was 25 mmol and the acetic acid was 15 mmol, keep the ultrasonic oxidation under the conditions of 50 ℃ for 24 h, and then the pH value was adjusted to 9 to 10 with ammolonia solution, 69.07% of rhenium compound can be recovered from the ILs. It has been proved that the recycled rhenium product is ammolonium perrhenate, and the purity is about 99%.

摘要: 以质量分数35%的过氧化氢水溶液及冰醋酸为氧化剂,采用超声氧化消解的方法从含铼离子液体中分离回收铼。当高铼酸盐离子液体为2.5 mmol时,超声氧化消解含铼离子液体的适宜条件为质量分数35%的H2O2水溶液为25 mmol、冰醋酸为15 mmol时,50 ℃条件下超声氧化24 h,使用氨水将溶液pH调至9~10。经回收得到铼化合物的最佳回收率为69.07%。实验结果表明,经以上过程得到铼产品为高铼酸铵,粗产品纯度为99%。
