The thesis aims to purify waste poly(vinyl chloride) (PVC) and chemically modify it using various aliphatic and aromatic amines to prepare functional polymeric membranes. The study focuses on evaluating the structural, thermal, and physicochemical properties of the modified PVC membranes and investigating their potential applications in environmental remediation, particularly for the removal of heavy metal ions (Co²⁺, Ni²⁺, and Fe³⁺) from aqueous solutions and for oil–water separation processes.

This study was conducted at the University of Baghdad / College of Science for Women / Department of Chemistry. Purified PVC was chemically modified and fabricated into cross-linked polymeric membranes. The prepared materials were characterized using Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), thermal analysis (TGA), and swelling measurements. Adsorption experiments for heavy metal removal and oil–water separation tests were performed to evaluate the efficiency and performance of the modified PVC membranes.

The most important recommendations reached by the thesis are:

1. Expanding the application of modified PVC membranes for the removal of other toxic heavy metal ions from wastewater.
2. Studying the long-term stability and reusability of the modified PVC membranes in repeated adsorption and oil–water separation cycles.
3. Investigating the effect of different cross-linking agents and polymer compositions on the adsorption efficiency and separation performance of PVC-based membranes.
