FTIR spectra of chitosan (CH), EDTA disodium (EDTA) and SE-CHEM. The samples with KBr pellet were measured (at ambient temp.) for FTIR-ATR analysis in the 500–4000 cm−1 spectral range. The C2 (SE-CHEM) showed absorption bands between 1676–1657 cm−1 and 1693–1667 cm−1, representing the amide linkage. The absorption bands between 2378 and 2373 cm−1 correspond to free acetate moieties
