Thermal characterization and sorption of FeIII ion by ternary polylactide–poly-3-hydroxybutyrate–chitosan compositions

Thermal transitions have been determined for different ternary compositions of polylactide and poly-3-hydroxybutyrate with chitosan from their TGA and DSC data. The sorption capacity of the ternary mixtures for Fe^III ion has been evaluated using the Langmuir model and found to increase with the chitosan content.
