Abstract

The structure of sodium salts of sulfated arabinogalactan (AG), obtained by sulfation of larch wood AG with sulfamic acid – urea mixture in the medium of 1,4-dioxane was investigated with the use of Raman spectroscopy, X-ray diffraction (XRD), scaning electron microscopy (SEM) and aromatic force microscopy (AFM) methods. The introduction of sulfate groups into the structure of AG was confirmed by appearance in Raman spectra new absorption bands characteristic for the deformation vibrations of d (SO3) at 420 cm-1 and d (O=S=O) at 588 cm-1, stretching vibrations n (C–O–S) at 822 cm-1, symmetric stretching vibrations ns (O=S=O) at 1076 cm-1, asymmetric stretching vibrations nas (О=S=O) at 1269 cm-1. According to XRD data the amorphization of arabinogalactan structure take place during it`s sulfation. The difference in the morphology of initial and sulfated arabinogalactans was established by SEM method. Initial arabinigalactan consists of particles of globular shape with size of 10–90 µm, but sulfates of AG – from particles of different shapes and sizes of 1–8 µm. According to AFM data the surface of film of arabinogalactan sulfates is formed by the rather homogeneous spherical particles with sizes near 70 nm. The mean-square value of the surface rounghness is equal to 33 nm.
