在N_2保护下,用钠汞齐将三氯化铕水溶液还原为二氯化铕溶液后,对其还原率进行了测定,还原率大于98%,可用于合成二价铕的配合物.
Under the protection of N 2, the reduction rate of europium trichloride aqueous solution was reduced to europium dichloride solution with sodium amalgam. The reduction rate was more than 98%, which could be used to synthesize divalent europium complexes.
