最近看文献,关于Al-HAP(Al-改性的羟基磷灰石)吸附氟离子的研究,其中有一段:(省略的内容应该是不影响的,小弟在手打,就不多写了)
...the -OH stretching vibrations at 3420 cm-1 also shifted to higher frequencies. The result indicated that the surface M-OH was active site and the quantitative substitution of the M-OH groups by F- played a key role in F- adsorption.
我想问一下,文献中通过吸附氟离子前后-OH伸缩振动频率的变化(意思是-OH变少了?),所得出的结论是否是可靠的。。。请大家帮忙分析一下~
