FT-IR
yöntemi, mantar çürüklük tahribatının tespiti, kimyasal değişikliklerin
karekterizasyonu için kullanışlı bir metoddur. Yapılan çalışmalarda mantarların
oluşturduğu kayıplar ağırlık üzerinden hesaplanmaktadır. Bu çalışmada Bakır azol
ve CX-8 maddeleriyle emprenye edilen ve 2 ay süreyle Trametes versicolor mantarına maruz bırakılan örneklerdeki kimyasal
değişimler FT-IR analizi ine incelenecektir. Elde edilen sonuçlara göre kontrol
ve %1 konsantrasyonda emprenye edilen örneklerde lignin, selüloz ve hemiselüloz
piklerinde azalma gözlenmiştir. %3 konsantrasyonda emprenye edilen ve mantar
testi uygulanan örneklerin lignin pikinde önemli bir değişme olmamıştır.  Emprenye işlemi ile O-H ve C-H grupları
modifiye edilmiştir ve ilgili pikler önemli oranda azalmıştır.

Chemical Characterization of Fungal Deterioration In Populus Alba By FT-IR

Öz

FT-IR analysis is one of the most useful
method for investigating fungal decays, characterizing the chemical changes in
the wood. The mass losses in wood caused by the fungi are calculated on the
basis of difference in weight. In this study, chemical changes of samples,
impregnated with copper azole and CX-8 and exposed to Trametes versicolor fungi for 2 months, were examined by FT-IR.
According to the results obtained, there was a decrease in lignin, cellulose
and hemicellulose peaks after impregnation at 1% concentration and for control
wood. No significant change was shown in the lignin peaks for the treated
samples (3 % concentration) exposed to the decay test. Results indicated that
O-H and C-H groups were modified by impregnation and related peaks were
significantly reduced.
