摘要

研究了新癸酸(HA)与1-(2-新炔酰胺乙基)-2-新炔-2-咪唑啉(L)在甲苯中以15% (v/v)的正癸醇为溶剂从硝酸溶液中萃取重系镧的方法。在平衡pH为6.0 ~ 6.5的范围内,发现了铒(III)的协同萃取。考察了平衡时间、温度、稀释剂性质、水相酸度以及一种萃取剂在另一种萃取剂固定浓度下的变化等因素的影响。温度在0 ~ 45℃范围内对提取过程无影响。考察了混合萃取剂萃取铒前后的FT-IR光谱,并测定了混合萃取剂对Er(III)的负载能力。实验数据表明,铒离子不与L直接配位,硝态氮离子不参与铒(III)的萃取。在平衡pH 5.0 ~ 6.0范围内,通过斜率分析法确定提取物为[Er(OH)A2·L]。随着pH的增加,[Er(OH)2A·L]成为主要的被萃取物。讨论了萃取机理。计算了Nd/Pr、Y/Pr、Dy/Y、Ho/Y和Er/Y分离因子,并证明了Er - Y对分离的可能性。

Synergistic Solvent Extraction of Erbium(III) using a Mixture of Neodecanoic Acid with 1-(2-Neononylamidoethyl)-2-Neononyl-2-Imidazoline
ABSTRACT The solvent extraction of erbium(III), representing heavy lanthanides, from nitrate solutions has been studied using a novel mixture of neodecanoic acid (HA) with 1-(2-neononylamidoethyl)-2-neononyl-2-imidazoline (L) in toluene with 15 % (v/v) of n-decanol. The synergistic extraction of erbium(III) has been found in the equilibrium pH range from 6.0 to 6.5. The effects of the equilibration time, the temperature, the nature of diluent, the aqueous phase acidity, and variation of one extractant at a fixed concentration of the other extractant have been investigated. The temperature had no effect on the extraction process in the range of 0–45°C. FT-IR spectra of the mixed extractant before and after extraction of erbium were examined, and the loading capacity of the mixed extractant for Er(III) was determined. The experimental data indicated that the erbium ion is not directly coordinated by L, and the nitrate ions are not involved in the extraction of erbium(III). In the equilibrium pH range between 5.0 and 6.0, the extracted species were determined to be [Er(OH)A2·L] by the slope analysis method. The increase in the pH leads to the dominance of [Er(OH)2A·L] as the main extracted species. The extraction mechanism is discussed. The Nd/Pr, Y/Pr, Dy/Y, Ho/Y, and Er/Y separation factors were calculated, and the possibility of the separation of the Er–Y pair was demonstrated.
