The main purpose of this work is study the influence of the insertion metal ions Ni (II) in the phosphogypsum produced by sulfuric acid attack of tricalcium phosphate. Indeed, the maximum content of heavy metals calcium sulfate that can absorb was determined. The added ions are (NiCl2, 6H2O) with mass concentrations ranging from 5% to 50%. The samples prepared were characterized by various methods, such as X-ray diffraction (XRD), infrared spectroscopy and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The results of this study showed that the limit of insertion of metal cations in calcium sulfate is limited to 30% for nickel.
