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。
Infrared spectra, infrared differential spectra and SIMS analysis of Al (OH) 3 + H3BO3, Al (OH) 3 and H3BO3 were carried out. The results show that there are two characteristic absorption peaks at 1423 and 1279cm-1 for Al (OH) 3 + H3BO3 samples, which are broader than those of H3BO3, indicating that in Al (OH) 3 + H3BO3 treatment, A new material was formed on the surface of Al (OH) 3, namely the adsorption complex of boron. The SIMS spectra of the boron adsorbed complex on the surface of aluminum hydroxide show that boron is highly dense on the surface of Al (OH) 3, which reflects that the proportion of boron to aluminum in this surface structure is different from the simple boron and aluminum mixture.
