Nickel (Ni) is an economically important metal characterized by its mechanical strength and anticorrosion properties. With the increasing industrial demand for Ni and the depleting accessible Ni primary ores, sustainable technologies are required for the recovery of this metal from alternative resources. In this study, adsorption using chitosan was investigated as a sustainable technique to recover Ni from sulfate (SO42-) and calcium (Ca) rich secondary resources. The effects of pH, contact… Expand

The Influence of Salt Anions on Heavy Metal Ion Adsorption on the Example of Nickel
TLDR
The calculated values of Gibbs free energy change ΔG0 confirm the higher adsorption of nickel ions in presence of sulfate ions, and suggest that higher anion valence leads to a higher advertisersorption capacity. Expand
