He bulk, as a result of rupture of hydrogen bonds amongst water molecules and polar functional groups. Around the the 8c), this hydrogen bonds in between water molecules and polar functional groups. On DSC curve (Figurerupture ofprocess corresponds to a distinct endothermic peak. The price the DSC curve (Figure 8c), increasing temperature a to 280.74 then of weight reduction for xanthan increases withthis procedure corresponds toupdistinct endothermic peak. The price of weight loss for xanthan increases with escalating temperature up to 280.74 C and decreases. Therefore, the key degradation of xanthan happens in one step. Within the selection of the then decreases. Hence, the principle degradation of xanthan happens in 1 step.

The endothermic impact around the DSC curve in the indicated interval is flatter and not as pronounced. The key decomposition of xanthan sulfate, in contrast for the original xanthan, occurs in two stages. The DTG curve has two pronounced peaks, with maxima at 226 and 286 C. The initial stage is almost certainly linked with the decomposition of sulfo groups (weight-loss 18.8 ). Throughout the second stage of decomposition (up to 300 C), xanthan “loses” 64 . Around the DSC curve, the decomposition of sulfo groups corresponds to a sharp and rather intense exothermic peak, with a maximum at 226 C, which, with a rise within the heating temperature, passes in to the endothermic zone. The endothermic impact within this area is most likely related with all the melting with the substance together with the simultaneous decomposition from the structure of xanthan sulfate; the latter statement is confirmed by the slope from the TG curve within this interval. Additional 12 of 16 heating in the sample to 600 C results in aromatization of your structure with the formation of a carbonized residue (fat reduction 79 ). 3.7. Atomic Force Microscopy 3.7.
