The regularities of iron (III) and nickel (II) ions sorption kinetics on super-thin basalt fiber (STBF) were studied. The correlation between the adsorption rate constants and the ions diffusion coefficients was established. The adsorption equilibrium for the iron (III) ion is well described by the Freundlich model, and for the nickel (II) ion – by the Langmuir model.
