• Description:
  Nickel solubilities in spent pickling solutions (i.E, HF-HNO3-H20 solutions) were measured as a function of HF and HN03 acid concentrations. The chemical analysis of the industrial pickling solutions and sludges were made. The stable phases observed in the sludges are FeF3*3H2O and (FeCr)F3*3H2O. Pure Ni and stainless steel type 316 were used in this study. The results showed that the solubility of Ni increased with increase in concentrations of HF in pickling solution at a fixed concentration HNO3. An excellent agreement between the experimental solubility data and the theoretical data was obtained. X-ray diffraction analysis showed that the solid solubility product formed is mainly NiF2*4H2O compound. [Description provided by NIOSH]
