Abstract
The physicochemical and sorption properties of MIU-S carbon sorbent have been studied. The studies were carried out on a model solution of nickel(II) sulfate containing an additional 400 mg/L sodium sulfate in the pH range of 5–8. It has been shown that the MIU-S sorbent is capable of removing nickel(II) ions from solution by the mechanism of simple monomolecular adsorption described by the Langmuir equation. The parameters of this equation are determined for different pH values of the model solution. It was found that, with an increase in the pH of the solution from 5 to 8, the efficiency of sorption of nickel(II) ions by the MIU-S sorbent increases. The sorption properties of MIU-S with respect to nickel(II) ions are compared with the properties of other carbon (coal) sorbents described in the literature.
