摘要
研究了D-314大孔聚丙烯酸阴离子交换树脂在中性体系中吸附、解吸钼和铼的条件和机制。结果表明,在常温下,溶液的pH=7.0,柱上流速为1.0ml.min-1时,D-314树脂分别对钼和铼有效吸附,然后用2%NH3.H2O-2%NH4NO3混合溶液,流速为4.0m.lmin-1,流出体积为16.5m.lmin-1,和6%NH3.H2O溶液,流速为2.0m.lmin-1,流出体积为13.0ml.min-1,分别对钼和铼进行淋洗解吸,分离系数KMo/Re=384,钼和铼各自的回收率分别为92.40%和83.96%。
The condition and mechanism of D-314 macroporous polyacrylic acid anion exchange resin absorbing and eluting molybdenum and rhenium in the neutral system were studied. The results showed that:molybdenum and rhenium can be effectively absorbed at room temperature when pH=7.0 at the flow rate of 1.0 ml·min-1 in the column,then molybdenum and rhenium could be eluted with 2%NH3·H2O-2%NH4NO3 mixture solution at the flow rate of 4.0 ml·min-1 with 16.5 ml and 6%NH3·H2O at the flow rate of 2.0 ml·min-1 with 13.0 ml...
