XRD graphs of chitosan (CH), EDTA disodium (EDTA) and SD-CHEM samples were measured using the X-ray diffractometer at a voltage of 45 kV. The XRD pattern for chitosan showed two diffraction peaks, one at 2θ = 20.37° and 2θ = 29.57°, while EDTA disodium diffraction peaks were at 2θ = 21.2°, 2θ = 26.5°, 2θ = 29.8°, 2θ = 34.3° and 2θ = 45.4°. SD-CHEM samples showed broad diffraction peaks at 2θ = 21.2°, 2θ = 23°, 2θ = 26.5° and 2θ = 29.8°
