研究了以0.15 mol/L的NH4Cl为底液,在自行设计的电解池中从90Sr母液中电沉积分离医用的90Y。控制阴极电流密度为0.6 A/cm2,电沉积40 min后,用0.1 mol/L的热盐酸洗脱后再次电沉积后得到医用90Y,二次电沉积后90Y与90Sr的分离系数大于1×106,90Y的洗脱收率大于70%。 In this paper, 90Y was electrocoagulatively separated from 90Sr mother liquor by using 0.15 mol / L NH4Cl as the bottom liquid in a self-designed electrolytic cell. After controlling the cathodic current density to 0.6 A / cm2 for 40 min, the electrode 90Y was eluted with 0.1 mol / L hot hydrochloric acid, and the electrode 90Y was obtained after electrodeposition. The separation coefficient of 90Y and 90Sr after the secondary electrodeposition was more than 1 × 106 , 90Y elution yield greater than 70%.
