摘要
本文用红外光谱研究了由不同铝离子浓度、不同羟铝比的羟基铝溶液交联而成的羟基铝交联蒙脱土。结果表明,交联剂的铝离子浓度及羟铝比对交联蒙脱土的红外光谱基本无影响,而焙烧温度则有显著的影响。分析比较经不同温度焙烧后的试样的红外光谱图,得出有关羟基铝交联蒙脱土热稳定性及结构变化的信息。
A number of hydroxyl-aluminium cross linked montmorillonites with different concentrations of A13+ ion and OH/A1 ratios have heen investigated hy infrared spec-troscopy. The results show that there are essentially no influence on the infrared absorption bands for the concentration of A13+ ion and OH/A1 ratio of the cross linging agent but significant change take place after heating the samples at various temperatures. Some important informations about the thermal stability and structural change of hydroxyl-aluminium montraorillonite can be obtained by comparison of the infrared spectra.
