萃取色谱,作为一种强有力的分离手段,已获得广泛的应用。我们合成了含N263萃取剂的树脂,树脂中N263最高含量可达60%(W/W),将此树脂用于常量铁与微量稀土的分离,方法简单、快速。一、N263萃取树脂的合成将装有搅拌器的三颈瓶置于恒温水浴中,加入分散剂、蒸馏水,在搅拌下升温,使分散剂溶解后,将水浴温度调至40℃投入预先配制好的有机相,调节搅拌速度,使有机相油珠大小合适,在85℃ Extractive chromatography, as a powerful means of separation, has found wide application. We have synthesized a resin containing N263 extractant, the highest content of N263 resin up to 60% (W / W), the resin used for the separation of trace iron and trace rare earth, the method is simple and fast. First, the synthesis of N263 extraction resin The three-necked flask equipped with a stirrer placed in a constant temperature water bath, adding dispersant, distilled water, heated under stirring, the dispersant was dissolved, the water bath temperature was adjusted to 40 ° C pre-formulated The organic phase, adjust the stirring speed, make the organic oil bead size appropriate, at 85 ℃
