| Abstract: | 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. |
