Definitions

  • the present invention is - Tsu 0 Ru Monodea to ⁇ to extract polishes and extractables ⁇ method of using it is used in the Kell and co Baltic extractables ⁇
  • the following formula is used as an extractant for separating nickel and cobalt by solvent extraction of copart from aqueous solution containing nickel and cobalt.
  • R t is an alkyl group having 8 to 10 carbon atoms each.
  • Alkyl phosphine is represented by the following formula.
  • the present invention relates to an extractant that solves the above questions.
  • R i and R t represent an alkyl group
  • R and R represent an alkyl group having 4 carbon atoms
  • the present invention provides an extraction agent for extraction and separation of an alkyl phosphonate monoalkyl ester represented by the formula:
  • R ⁇ represents an alkyl group
  • R and R represent an alkyl group having 4 carbon atoms
  • R i is an alkyl group having 8 carbon atoms.
  • Alkyl phosphonic acid mono-alkyl ester represented by the formula:
  • the target liquid to which the extractant of the present invention is used is a mixed solution of -nickel and cobalt.
  • the mixture is-
  • Scrap such as so-called mixed sulfuride, superalloy, etc., containing Ni, Co Ni, Co
  • the extractant is diluted with a diluent to obtain its surface area. It is usually diluted at a ratio of 1:10 to 10: 1.
  • a diluent kerosene, dispazole or the like is used.
  • the mixture of cobalt and nickel is brought into contact with an organic solvent obtained by diluting the above-mentioned extractant at a ratio of 1:10 to 10: 1.
  • the contacting pH is 3-8, preferably pH 4-7.
  • the temperature of the liquid when it comes into contact is around 70 from room temperature.
  • the contact between the organic solvent phase and the aqueous phase is brought under a predetermined condition for a certain period of time by using any contact device used for liquid-liquid extraction, and then the mixture is improved
  • Examples of the extractant include n-butylphosphonic acid mono-n-butyl ester, and 2n-butyl phosphonic acid mono-mono-2 'ethyl.
  • Xyl 'ester diisopropyl, phosphonic acid, mono, 2-ethylhexyl. Esters and the like.
  • the extractant was n-butyl'phosphonic acid, mono-n-octyl ester, and nickel and cobalt in aqueous solutions containing nickel and cobalt. was extracted and separated.
  • An organic solvent having an extractant of 1 ⁇ m and a diluent of 84 was contacted with the above aqueous solution at 0 ° C. for 5 minutes.
  • the dispersant used was Dispasol.
  • the separation factor ⁇ between nickel and cobalt was extremely high, ranging from 10 to 250.
  • the kinematic viscosity is as follows: the Co concentration in the organic solvent is 15 ⁇ 2 / i,
  • the extraction separation coefficient was as low as S, 45 4. For this reason, it is not possible to easily obtain high-purity Ni and Co metals as compared with the present invention.
  • the extraction processing was performed so that the Co concentration in the organic solvent containing the above-mentioned extractant was 15 52 ⁇ , and as a result, the kinematic viscosity was 39.4 cSt (6 0 ° C). Since the kinematic viscosity was more than 150 cSt (60 ° C), favorable operations could not be performed.
  • the present invention provides a very simple means of solvent extraction from Ni and Co-containing alloy scraps, spent catalysts, etc.
  • Ni it is possible to separate Ni with high purity: it is possible to reduce the amount of extractant used by reducing the amount of extractant used, making it possible to reduce the amount of extractant used. It is beneficial.
