冠醚萃取Sm^(3+)后在有机相中的电反萃

RECOVERY OF SAMARIUM FROM CROWN ETHERCOMPLEX SOLUTIONS BY THE ELECTROCHEMICAL METHOD

应用电化学方法和阳离子交换隔膜,在含有苦味酸根的有机相体系中,可以有效的分离Sm^(3+)与冠醚形成的配合物,并且阳极液可以循环利用。当阳极液中C_(Sm)^(3+)=2.65×10^(-3)mol/L,阴极液C_HNO_3=0.1mol/L,在室温下,应用电化学方法反萃0.5h,分离率达57.48％。

Using an electrolytic cell with a cation-exchange membrance, The complex formed by Sm3+ and crown ether can bedissociated effectively. Furthermore, the catholyte solution can be recirculated. At room temperature,the dissociation can be rearched 58. 48% with opposite recover time 0. 5h by electro-chemical method.
