Özet:

 


In this study, Trapa natans nut
collected from the costs of Inkumu-Bartin was analyzed according to its lignin content.
Acid-insoluble lignin content was determined according to TAPPI T222om-02 as
28.31%. TGA and FTIR analyses were performed. 


FTIR analysis indicated that Trapa
natans contained cellulose, hemicelluloses and lignin. The peaks at
1506-1510 cm-1 in both samples are characteristic peaks for the
lignin components due to C = O and COO-non-symmetric stretching vibrations in
the aromatic rings of the lignin structure. 1510 cm-s peak is found
in the literature as lignin’s fingerprint peak.  The peaks at 1230-1270 cm-1 band
show the vibrations of guayasil ring with CO tension in lignin and
hemicelluloses. Around the peaks of 900, 1025, 1030 and 1050 cm-1
bands cellulose’s O-H, C-H and C-O-C type bonds are seen. When TGA analyzes are
examined, approximately 4.5% of the sample is lost from 30 °C to 200 °C. At
these intervals, samples generally lose volatile constituents and moisture.
From 200 to 271 °C 4.6% of the weight is lost. The decrease in this range may
be due to the decomposition of cellulose and hemicelluloses. The DTG curve
shows maxima weight-loss occurring at 349 °C. The weight-loss in the range from
271-352 °C is about 50%. Pure lignin sample’s TGA and DTG curve results show
10%, 50%, and 70% weight-losses at 233 °C, 489 °C, and 1167 °C respectively. According
to these results, dominantly lignin and small quantities of cellulose and
hemicelluloses are present in trapa samples.
