【摘要】 对Ａｌ（ＯＨ）３＋Ｈ３ＢＯ３，Ａｌ（ＯＨ）３，Ｈ３ＢＯ３等样品进行了红外光谱、红外差分谱以及Ａｌ（ＯＨ）３＋Ｈ３ＢＯ３的二次离子质谱（ＳＩＭＳ）分析。结果表明，Ａｌ（ＯＨ）３＋Ｈ３ＢＯ３样品在１４２３和１２７９ｃｍ－１处有２个特征吸收峰，这些峰与Ｈ３ＢＯ３表现出的吸收峰相比，峰带更宽，说明在Ａｌ（ＯＨ）３＋Ｈ３ＢＯ３处理中，Ａｌ（ＯＨ）３表面形成了一种新物质，即硼的吸附络合物。氢氧化铝表面硼吸附络合物的ＳＩＭＳ图谱表明，硼在Ａｌ（ＯＨ）３表面高度密集，反映了这一表面结构状况中铝硼原子比例不同于简单的硼铝混合物。更多还原

【Abstract】 Infrared spectra,infrared differential spectrum as well as second ion mass spectrum（SIMS） analysis on Al（OH）3+H₃BO₃, Al（OH）₃ and H₃BO₃ solid samples were used to characterize the structural regimes of boron on the surface of aluminum hydroxide.　Al（OH）₃+H₃BO₃ sample had two resolved peaks in 1423 cm and 1279 cm-1 which were wider than the corresponding peaks of H₃BO₃. These wide peaks were attributed to the formation of a new substance, i. e. boroncontaining adsorption complex on the surface of Al（OH）₃. The second ion mass spectrum of Al（OH）₃+H₃BO₃ sample indicated that high concentrated boron on the surface of Al（OH）₃ reflected the atomic ratio of B and Al, and that boroncontaining adsorption complex was not a simple blend of B and Al.更多还原
