  Application:
  DZ272 is to separate Nickel-Cobalt elements, and separate rare earth elements as the substitution of P204 or P507. DZ272 has high separation coefficient, can reduce the extraction steps powerfully. The extracting curve of DZ272 in sulfuric acid medium is as follows:
  
  Stability:
  DZ272 can be in the appropriate conditions of pH value and temperature for a long time. The physical and chemical properties of DZ272 are stable. There is no obvious phenomenon of be hydrolysis or extraction selectivity is reduced etc.?
  Loss of dissolution:
  We tested the loss of dissolution of DZ272 in aqueous phase conditions of different pH value and aqueous salt concentration. The solubility in aqueous phase is proportional to the pH value, but is inversely proportional to the concentration of aqueous salt, which is same as normal acidic extractant. The loss of dissolution is less, the dissolution is same as other commercial extractant.
  Package and storage:
  200 kg plastic barrel of 1000L IBC tank. The product must be airtight and stored in dry and cool places. It can’t be stored with alkali products together.
