| 摘 要： | 一、前言离子交换法分离铀同位素中,用Ti~(3 )作为UO_2~(2 )的还原剂。钛在该条件下水解成一白色二氧化钛沉淀物,甚至把离子交换树脂粘结成块,使树脂中毒。而二氧化钛对铀又是良好的吸附剂,它干扰谱带的形成和分离效果。通过反复试验,找出了一种溶解二氧化钛沉淀物,并再生离子交换树脂的方法。先用

| Abstract: | The insoluble titanium dioxide which is produced from hydrolysis of Ti~(4 ) canbe dissolved rapidly in hot solution containing 0.25 mol/1 NaOH and a definitequantity of H_O_2. A ion exchange resin poisoned by the titanium dioxide precipi-tate can be regenerated with 2 mol/1 HCl and above mentioned solution. Theperformance of resin regenerated did not change. |
