考察了用D35 4树脂从解钼液中回收钨钼的情况。在pH =3,接触时间为 40min时 ,D35 4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 2 38mol/L湿树脂 ;用 1 0 %NaOH做解吸剂 ,解吸效果很好 ,解吸液中WO3和Mo的最大浓度分别可达 1 0 0g/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。
The case of recovering tungsten and molybdenum from the molybdenum solution using D35 4 resin was examined. At pH = 3, the contact time of 40min, D35 4 resin can adsorb more than 97% of tungsten and molybdenum, tungsten and molybdenum co-adsorption of saturated adsorption capacity up to 0 2 38mol / L wet resin; with 10% NaOH desorbent, The desorption effect is very good. The maximum concentrations of WO3 and Mo in the desorption solution are up to 100 g / L and 36 g / L, respectively. The resin is regenerated with alkaline sodium hypochlorite. After the hydrochloric acid is transformed, the repeated use is stable.
