一、前言众所周知,吸收光谱法不仅是分析化学领域中的一种重要分析手段,而且在生物化学、物理学、无机化学及物理化学等方面,也有广泛的应用。但是对于某些物理状态的试样,如非均质(悬浮物、凝胶、生物组织),固体或半固体(粉状物、涂敷材料、膜层),水敏化或空气敏化的物质,以及无损分析,这种分析方法就存在困难。对均质固体用反射光谱法研究,要求试样有高的反射率和超清洁的表面,需要复杂的高真空装置,并且不容许存在杂散
I. Preface As we all know, absorption spectrometry is not only an important analytical method in the field of analytical chemistry, but also widely used in biochemistry, physics, inorganic chemistry and physical chemistry. However, for some physical state samples, such as heterogeneous (suspended solids, gels, biological tissues), solid or semi-solid (powder, coating material, membrane), water-sensitized or air-sensitized Material, and non-destructive analysis, there are difficulties with this method of analysis. Reflectance spectroscopy studies of homogeneous solids require that the sample have high reflectivity and super clean surfaces, require complex high vacuum devices, and do not allow the presence of stray
