Synthesis and Characterization of New Polymers Containing Bis 1,2,4-Triazole Ring and Used in the Purification of Wastewater from Copper Ion

In this study, two types of polymers containing bis 1,2,4-triazole were prepared (poly thioether and poly thioester) by condensation polymerization. These polymers were characterized by FTIR, 1 H NMR, DSC and TGA techniques. Also, intrinsic viscosities were measured to estimate the molecular weight...

Description
Summary:In this study, two types of polymers containing bis 1,2,4-triazole were prepared (poly thioether and poly thioester) by condensation polymerization. These polymers were characterized by FTIR, 1 H NMR, DSC and TGA techniques. Also, intrinsic viscosities were measured to estimate the molecular weight of the polymers. We use these polymers in treating wastewater containing heavy metal ion, Cu +2 . The effect of time on the efficiency of Cu +2 ion removal in 25°C was investigated. Results showed that when researchers used poly thioester to removal the copper ion from wastewater, the ability of removal is better than when poly thioether is used.
