项目摘要

From the viewpoint of environment protection and forest saving, there has been recently a global tendency to reconsider development of wood-based materials. Effective utilization of thinnings, bark or waste wood has been studied widely. Above all, reuse of construction waste wood is an important point. Thus, it is essential for safe reuse to detect foreign materials in wood because foreign materials are often hazardous or toxic chemicals.For the purpose of establishing an easy and quick xenobiotic analytical method, we investigated the characteristics in wood analysis of Raman, infrared, X-ray fluorescence spectroscopy, etc., and proposed an analytical system for wood-based materials including no wet processes by a combination of these analytical techniques. The system is as follows.First, Raman or infrared measurements for waste wood are performed in order to detect adhesives, preservatives, or paints. When xenobiotics are found in waste wood, they are identified and further investigated the distribution by microscopic spectroscopy. Volatile organic compounds are quantified by gas chromatography if formaldehyde resin was used. When inorganic compounds are expected to be included in woody materials, we analyze elementally the materials by X-ray fluorescence spectrometry.Our analytical system has not come in practice yet. We are currently improving the system for the sake of downsizing and simplification

从环境保护和森林节约的角度出发，近年来全球出现了重新考虑木质材料开发的趋势。间伐物、树皮或废材的有效利用已得到广泛研究。首先，建筑废弃木材的再利用是一个重要的问题。为了建立一种简便、快速的木材异物分析方法，本文研究了木材异物的拉曼光谱、红外光谱、X射线荧光光谱等分析方法的特点，并提出了一个分析系统，用于木材基材料，包括通过这些分析技术的组合没有湿处理。该系统如下：首先，对废木材进行拉曼或红外测量，以检测粘合剂、防腐剂或油漆。当在废木材中发现异生物质时，通过显微光谱法对其进行鉴定并进一步研究其分布。如果使用甲醛树脂，则通过气相色谱法定量挥发性有机化合物。当木质材料中含有无机化合物时，我们采用X射线荧光光谱法对木质材料进行元素分析，我们的分析系统尚未投入实际应用。我们目前正在改进该系统，以便精简和简化
