Based on the thermodynamic stability models of Ni minerals, NiFe2O4 (nickel ferrite) and Ni3(PO4)2 seem the most probable solid phases that could form in soils during Ni sorption. An earlier study showed that the sorption of Ni in different soils was significantly correlated to suspension pH, total Fe, and surface area, but was poorly correlated to the cation exchange capacity of the soils studied. The objective of this research was to investigate the probability of Ni solid phase formation in soils.
