Abstract

Purified (in acetone, at 50° C for 72 h), post-consumer PVC waste was grafted with 1,4-benzodioxane6-amine and 2-aminobenzimidazole to increase its ability to remove ions from wastewater (from the Beja region, Tunisia). The PVC waste was characterized by IR spectroscopy, differential thermal analysis (DTA) and elemental nitrogen analysis. The ability of modified PVC waste to remove ions [sulphates ions (SO4 2-), nitrates ions (NO3 -), chloride ions (Cl-), carbonates ions (CO3 -), metal ions (Mg2+, Zn2+, Na+, K+…)] from wastewater was assessed based on ion conductivity measurements. It was found that modified PVC waste shows a greater efficiency in the removal of ions from wastewater than unmodified waste.
