Abstract: PURPOSE:To separate metal ions continuously and effectively with a single process by feeding a soln. contg. >=2 kinds of metal ions and complex-forming anions to a multi-cell electrolytic cell installed with an anion exchange membrane and/or a cation exchange membrane as diaphragms and proceeding electrolysis in the cell. CONSTITUTION:A cathode 7 and an anode 8 are disposed to an electrolytic cell 1. A cathode chamber 2, an anode chamber 3, and an intermediate chamber 6 are constituted by arranging alternately a cation exchange membrane 5 and an anion exchanging membrane 4 in the order from the cathode side 7 and arranging the membrane 5 to face the anode. A soln. contg. metal ions and complex-forming ions is fed to the electrolytic cell 1 from the intermediate chamber 6, and a soln. of a salt such as NaCl, etc., is fed from the cathode chamber 2 and the anode chamber 3, to proceed electrolysis. Thus, metal cations in the soln. contg. >=2 kinds of metal ions migrate to the cathode chamber 2 through the cation exchange membrane 5. On one hand, metal complex anions migrate to the anode chamber 3 through the anion exchange membrane 4, but metal ions having small ionic characteristic do not migrate and are left in the chamber 6 in undissociated state. Thus, metal ions are separated.

Abstract: PURPOSE:To prevent the generation of scaling, by placing a stirring blade of a 1st stirring zone set in a range from the bottom of a tank to specific height, restricting the existing range of the blade within the circumferential part in the tank, setting a 2nd stirring zone above the 1st stirring zone and providing a stirring blade in the 2nd zone. CONSTITUTION:A rotary shaft 3 suspended vertically along the center axis of a reactor 1 is furnished with a stirring blade 4 of a 2nd stirring region l2 and a stirring blade 8 of a 1st stirring zone l1. There is no blade at the rotary center part of the stirring blade 8 and the rotational speed is maintained nearly the same level over the whole range in the radial direction of the leg 6 and the arm 7.
