研究了1-苯基-3-甲基-4-己酰基吡唑啉酮-5(PMHP)、2-噻吩甲酰三氟丙酮(TTA)、甲基膦酸二异戊酯(DiAMP)和二戊基亚砜(DASO)四元萃取剂的甲苯溶液从高氯酸钠底液中萃取钕的行为。实验发现有明显的四元协萃效应。用斜率法测定了四元协萃络合物的组成为NdAT_2BS及NdA_2TBS,它们的四元协萃平衡常数分别为K_(NdAT_2BS=5.2及K_(NdA_2TBS=0.88(25℃)。
The effects of 1-phenyl-3-methyl-4-hexanoylpyrazolone-5 (PMHP), 2-butanoyltrifluoroacetone (TTA), DiAMP and Extraction of neodymium from sodium perchlorate base solution with toluene solution of dipentyl sulfoxide (DASO) quaternary extractant. Experiments found that there is a clear quadruple synergistic effect. The composition of the quaternary complex complex was determined by the slope method. The equilibrium constants of the quaternary complex were Nd_ (2) B_2 = 5.2 and Nd_ (2 TBS) = 0.88 (25 ℃).
