The sorption properties of waste facade, brick, and asphalt sample towards
Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were
investigated. The highest sorption capacity was found for Ni(II) ions, while
the most effective sorbent was facade. Simplex Centroid Mixture Design was
used in order to investigate the sorption processes of ions from solutions
with different composition as well as the competition between the cations.
Based on the statistical analysis results, the equations for data modeling
were proposed. According to the observations, the investigated solid matrices
can be effectively used for the liquid radioactive waste treatment.
Furthermore, the applied methodology turned out to be an easy and operational
way for the investigations of multicomponent sorption processes.
