Abstract

The solid-liquid extraction is one of the most used methods for protection of the environment against organic and inorganic pollutants. The hybrid materials have been synthesized by a simple method from natural clay and modified poly(vinyl chloride) (PVC). The obtained products were characterized by various techniques, infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), and differential thermal analysis (DTA). The final materials were successfully used for entrapping heavy metal ions (Fe, Cu, Cd, Zn, Pb, Mn, and Co). The quantities of adsorbed metal cations were determined by atomic absorption analysis. It has been revealed that the metals extraction was governed essentially by the affinity between the functional groups of the hybrid material and the investigated metal ion. The cations are extracted in the following decreasing order of effectiveness: Fe³⁺ > Cu²⁺ > Co²⁺ ≈ Mn²⁺ > Pb²⁺ > Cd²⁺ ≈ Zn²⁺.
