Abstract

New polymers with potential application in a waste water purification from inorganic contaminants were synthesized via a chemical modification of poly(vinyl chloride) by "click” method based on copper(I)-catalyzed Huisgen reaction. The structure of the resulting polymers containing 1,4-disubstituted triazole units was confirmed by infrared spectroscopy (ATR-FTIR), nitrogen elemental analysis and differential thermal analysis (DTA). The obtained polymers were subsequently used in the elimination of nitrate ions and metalions from the wastewater of Beja region (Tunisia). It was found that new polymers were most efficient in capturing of zinc ions, the average extraction percentage of Zn2+ was 28%, while the average extraction percentage of nitrates did not exceed 12.5%. The selectivity of the binding of investigated ions can be arranged in the following order: Zn2+> NO3–> Ca2+> Mg2+.
