WebIn the gravimetric determination of nickel in steel, the Ni ions are brought in solution by dissolving the steel sample in concentrated acid. These are then precipitated from a ... WebThe thermodynamic factors and kinetics analysis demonstrated that the bioprocess was exothermic, favourable, and spontaneous at 298–318 K. Finally, the biosorption of nickel ions on SB-AP was explained by four proposed mechanisms based on the network structure of cellulose, lignin, N-acetyl-β-D-glucosamine, and β-d-glucosamine units.
