Abstract

Data on the synthesis and sorption properties of natural calcium aluminosilicates modified by poly-1-vinyl imidazole (PVIm) and poly-4-vinyl pyridine (PVP) are presented. The fullest recovery of nickel (II) ions from low-concentration solutions is observed for PVP-modified aluminosilicates. Adsorption of nickel (II) ions by PVIm-modified aluminosilicates is best described by the Freundlich adsorption model. In the case of PVP-modified aluminosilicates, the Langmuir model is more adequate. The free adsorption energy values indicate that the interaction between nickel (II) ions and modified aluminosilicates is of chemical nature.
