to highlight differences in the composition of fucoidans, alginates and carrageenans. Different classes corresponding to the season can be distinguished by statistical multidimensionnal analysis (Principal Component Analysis) showing that the structure of algal polysaccharides, related to bioactivity, depends...
Each FTIR spectrum showed a broad peak around 3600–3200 cm−1 followed by a peak around 1600–1300 cm−1, 1200–1000 cm−1, and 800–600 cm−1, indicating the existence of hydrate and hydroxyl (OH−) which were present in the cellulose and hemicellulose of the jute fiber [46...
(Varian Technologies, Palo Alto, CA, USA). Spectra were collected over the range of 4000–700 cm−1at 4 cm−1resolution. Interferograms of 64 scans were coadded followed by Beer–Norton apodization. The absorbance spectra were ratioed against the blank ATR crystal spectrum collected as ...
