A novel eco-friendly source of cellulose acetate extracted from Astragalus gombo seeds: thermal, structural, and morphological characterization

In this research, cellulose derivatives were extracted from the plant Astragalus gombo. This research sought to create a new cellulose acetate source derived from Astragalus gombo. Preliminary treatment, acetylation, hydrolysis, and precipitation, followed by purification, comprised the five processes involved in producing cellulose acetate. This arrives after several steps of cellulose extraction carried out earlier with an extremely high purity level. Scanner electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis were used to study and find out more about cellulose acetate. Its Fourier transform infrared spectroscopy spectrum showed that acetate groups replaced practically all hydroxyl (O-H) groups; also, the analysis showed the carbonyl (C = O) group at 1738 cm(-1) and the (C-O) group at 1217 cm(-1) region. The morphology of the obtained cellulose acetate consisted of cylindrical fibers and a perforated layer. The thermal analysis showed that cellulose acetate from Astragalus gombo possessed thermal properties compared to other studies. These findings demonstrated that Astragalus gombo could be successfully exploited in extracting cellulose acetate and substantiated its status as an innovative, environmentally friendly source.
