Abstract
The ultraviolet and infrared spectra of dioxane lignin from bamboo were investigated. 1. Spectrum curve type considerably resembled that of wood lignin. There were 3 absorption peak positions at 210nm(max. peak), at 260-270nm(shallow mini. peak), at 280nm(lower max. peak) as in the wood lignin spectra. 2. The lower minimum peak near at 280 nm is the typical peak of lignin. This peak does not exist exactly at 280 nm but from 282nm to 285nm in this bamboo UV spectra. The absorption intensities are equal in this region and the peak is not sharp. 3. The absorption band of aromatic nucleus is near at wave number
맹종죽, 왕대, 솜대 Dioxane Lignin의 UV, IR spectrum의 특징(特徵)을 조사(調査)하여 본 바, 그 결과(給果)를 요약하면 다음과 같다. 1. UV spectrum에 있어서는 일반적(一般的)인 Lignin spectrum과 같이 Maximum peak, Shallow minium peak, Minimum peak의 3개소(個所)를 보였는데 Max. peak는 210nm 부근(附近), Shallow peak는 260-270nm에, Minimum peak는 280nm부근(附近)에 있었다. 2. 280nm부근(附近)의 Minimum peak는 Lignin이 갖는 특징적(特徵的)인 peak로서 일반(一般) 침엽수재(針棄樹材) Lignin이나 활엽수(闊葉樹) Lignin과는 달리 282-285nm에서 흡광도(吸光度)가 꼭 같아 아주 완만한 peak 를 보여 주었다. 3. IR spectrum에 있어서는 방향핵(芳香核) 흡수대(吸收帶)는
