Mantar Tahribatına Uğramış Titrek Kavak Odununun FT-IR Yöntemiyle Kimyasal Analizi

Öz

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.
