Synthesis and Characterization of Eco-friendly Amino Polylactide Foam (APLAF) Active to Remove Palladium and Copper Ions in Water and Wastewater

One of the methods used to remove heavy metal ions from wastewater is the application of polymer materials through the adsorption process. In this study, the use of synthesized eco-friendly amino polylactide foam (APLAF) is reported for this purpose. The synthesized APLA was characterized via ATR-FTIR, H-1-NMR, and GPC, while the thermal properties of APLAF were studied with TG/DTG/DTA analyses and the surface morphology was tested with SEM analysis. The metal adsorption studies were carried out by the immersion test under Pd(OAc)(2) and Cu(OAc)(2) solutions at different times and pH. The analysis results show the successful synthesis of APLAF as a potential adsorbent. In this respect, the prepared adsorbent was used to remove the metal pollutants from the aquatic environment. As a consequence of removal experiments, the APLAF has the optimum adsorption at a pH of 7.5 for Pd(II) and Cu(II) metal ions, while the highest adsorption was obtained after 45 min of adsorption process and an optimum initial concentration of 20.4 mg/L.
