用咪唑丙基改性的硅胶表面吸附乙醇和丙酮溶液中的MX2（M = Mn、Ni、Cu、Zn和Cd； X = Cl、Br和I）和fecl3。用Langmuir方程确定了吸附量和吸附强度。研究了溶剂、温度和功能化程度对吸附的影响。功能化二氧化硅的红外光谱记录在1700 ~ 1300 cm−1之间。在金属-碱氮相互作用下，咪唑骨架振动的频带转移到更高的频率。
Silica gel surface modified with imidazolylpropyl group was used to adsorb MX2(M = Mn, Ni, Cu, Zn, and Cd; X = Cl, Br, and I) and FeCl3from ethanol and acetone solution. The adsorption capacity and the intensity of the adsorption were determined by using the Langmuir equation. The influences of the solvent, temperature, and degree of functionalization on the adsorption were also studied. The infrared spectra of the functionalized silica were recorded between 1700-1300 cm−1. The bands of the imidazole skeletal vibrations are shifted to higher frequencies upon metal-to-base nitrogen interaction.
