摘要
利用离子交换法对淋洗液中铼的富集进行了研究,结果表明,采用凝胶型强碱性阴离子树脂201×7可以较好地吸附淋洗液中的铼,吸附后先用5%NH4OH+5 g/L NH4Cl解吸掉大部分的钼,再用2 mol/L的NH4SCN解吸铼,可以得到含铼1 g/L以上的富铼溶液。
Enriching rhenium dissolving in washing water by ion exchange process was researched, result shows that rhenium could be adsorbed by 207 × 7 resin easily, molybdenum could be mostly desorbed by 5% NH4OH＋5 g/L NH4Cl solution, then 2 mol/L NH4SCN solution was used to desorb rhenium. The concentration of desorption solution was higher than 1 g/L.
