Hello,
TGA curves of my biochar and magnetic biochar products that I produced with walnut, rose and sawdust are attached.
I observe a sudden mass loss of 2-3% at the temperature point of 750 degrees throughout.
In my literature review, I could not find a reason to explain this loss.
What could be the reason for this mass loss observed in all of them at the same temperature and in the same amount?
thank you so much.
Dear Sevda.
Dou you have DTA curves simultanous of this TGA curves? This phenomenon is common in biofuel materials. It occurs due to an intense burning of the material at high temperatures, in which a highly energetic group is burned. The simultaneous DTA curve confirms this.
I suggest you try a TGA analysis with a smaller mass, ~1.5 mg.
Hello Sevda,
Is this TGA analysis done in a N2 environment ? If so, is O2/air introduced at any point?
Dear Sevda, have you tried running without any sample? By doing this you can eliminate if this is a true sample transition or an instrument induced signal.
