Abstract

We present X-ray fluorescence measurements of biopolymer chitosan [C6H11NO4]n and chitosan cross-linked with ethylene glycol diglycidyl ether (EGDE). Changes in the fine structure of resonantly excited O Kα X-ray emission spectra (XES) of unmodified chitosan are attributed to the excitation of non-equivalent oxygen sites belonging to -OH, -O- functional groups. The comparison of the nonresonant nitrogen Kα XES of unmodified chitosan cross-linked with EGDE does not show any differences, which excludes the model of chemical structure according to which EGDE is linked to chitosan via the amine group.
