Information
Solvent extraction experiments with Alamine336 from chloride solutions containing copper, nickel and cobalt have been performed to separate copper. The separation of copper from nickel and cobalt was dependent on the concentration of chloride ion and that of Alamine336. By utilizing the difference of complex formation constants between metal ions and chloride ion, it was possible to separate copper from nickel and cobalt by adjusting the concentration of chloride ion. Separation of copper from loaded organic phase was also possible by controlling the concentration of chloride ion in the stripping solution.
구리, 니켈, 코발트를 함유한 염산용액으로부터 추출제로 Alamine336을 사용하여 구리를 분리하기 위해 용매추출실험을 하였다. 니켈과 코발트로부터 구리의 분리성은 Alamine336의 농도와 수용액에서 염소이온의 농도에 큰 영향을 받았다. 금속이온들과 염소이온간의 착물형성상수의 차이를 이용하여 수용액에서 염소이온의 농도를 조절함으로써 구리를 분리하는 것이 가능하였다. 구리와 코발트가 추출된 유기상으로부터 탈거액의 염산농도를 조절하여 구리를 분리하는 것이 가능하였다.
