摘要

我们用红外光谱法研究了猛犸象牙的结构，包括热处理后的结构。揭示了象牙成分的整个官能团复合物-羟基磷灰石，胶原蛋白和水。胶原蛋白在红外光谱中由酰胺和脂肪基团的特征吸收带表示。在600℃热处理后，有机部分从样品中完全去除。羟基磷灰石以碳酸盐取代的形式存在于象牙骨组织中;900℃的热处理除去样品中的碳酸盐阴离子和水，使羟基磷灰石从非化学计量态转变为化学计量态。

Study of the Structure of Mammoth Tusk by IR Spectroscopy

We studied the structure of the mammoth tusk by infrared spectroscopy, including after heat treatment. The entire complex of functional groups of the tusk components—hydroxyapatite, collagen, and water—was revealed. Collagen is represented in the IR spectrum by the characteristic absorption bands of amide and aliphatic groups. After heat treatment at 600°C, the organic part is completely removed from the sample. Hydroxyapatite occurs in the tusk bone tissues in a carbonate-substituted form; the heat treatment at 900°C removes the carbonate anion and water from the sample, transiting hydroxyapatite from a nonstoichiometric state to a stoichiometric one.

期刊介绍： Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
