YbSO_4 purification by an electrolytic reduction method from Tm-Yb-Lu concentrates in sulphate medium was studied, in which Ru-Ir-Ti alloy nets and mercury were used as anode and cathode respectively under normal atmosphere without nitrogen or argon gas protection. 研究了以钌铱钛合金网和汞分别为阳、阴电极,在无气氛保护条件下,采用电解还原方法从铥、镱、镥硫酸盐溶液中分离提纯镱的过程。
In a medium of weak acidic amygdalic acid, niobium(ⅴ) can be reduced at dropping mercury cathode and then a polarographic wave is observed. 在弱酸性的杏仁酸底液中,铌(Ⅴ)能在滴汞电极上还原,产生一个极谱波;
Researches on electrolysis of rare earth elements at mercury cathode ⅺ. deposition of Rare Earths 稀土元素的汞阴极电解&Ⅵ.稀土元素的电沉积
In citric acid praseodymium could be quantitatively deposited at mercury cathode, while the deposition percentage of neodymium is 97%. 镨在柠檬酸溶液体系中可定量地进入汞相,钕的电沉率亦达97%左右。
