| 摘 要： | 考察了用Ｄ３５４树脂从解钼液中回收钨钼的情况。在ｐＨ＝３，接触时间为４０ｍｉｎ时，Ｄ３５４树脂能吸附９７％以上的钨钼，钨钼共吸附的饱和吸附容量可达０．２３８ｍｏｌ／Ｌ湿树脂；用１０％ＮａＯＨ做解吸剂，解吸效果很好，解吸液中ＷＯ３和Ｍｏ的最大浓度分别是可达１００ｇ／Ｌ和３６ｇ／Ｌ；树脂用碱性次氯酸钠再生，盐酸转型后，重复使用性能稳定。

| Abstract: | Investigation is made on the recovery of Mo and W from Mo stripping solution with D354 resin. >97% W and Mo is absorbed with D354 at pH=3 and contact time 40min. And the saturated absorbing capacity from W/Mo coadsorption can reach 0.238 mol/ml wet resin. The stripping results are excellent with 10% NaOH as strippant,the max concentration of WO 3 and Mo in the stripping solution can reach 100 g/l and 36 g/l respectively. The resin features stable reusability when regenerated with alkali NaClO and transformed by HCl. |
