Annotatsiya

A new anion-exchange material was synthesized via direct, solvent-free amination of chlorinated polyvinyl chloride (CPVC) with diethylenetriamine (DETA), avoiding organic solvents and simplifying the synthesis. The effects of reaction temperature (50–120 °C) and duration (2–5 h) on ion exchange capacity (IEC) were investigated, showing saturation at ~100 °C and 4 h (IEC ≈ 3.5 meq/g); 110 °C and 4 h were selected as optimal conditions. FTIR confirmed successful amination through new N–H/C–N bands and reduced C–Cl intensity. TGA showed that amination lowers the degradation onset, but the product remains stable up to ~190–200 °C, suitable for water-treatment use. Potentiometric titration revealed three distinct amine-type ion-exchange sites, consistent with the primary and secondary amine groups of DETA. The resulting CPVC-DETA material offers a simple, low-cost route to chlorine-containing polymer-based anion exchangers for water treatment.
